Hamstring Muscle Injuries Hamstring muscle injuries — such as a "pulled hamstring" — occur frequently in athletes. They are especially common in athletes who participate in sports that require sprinting, such as track, soccer, and basketball. A pulled hamstring or strain is an injury to one or more of the muscles at the back of the thigh. Most hamstring injuries respond well to simple, nonsurgical treatments. Anatomy The hamstring muscles run down the back of the thigh. There are three hamstring muscles: Semitendinosus Semimembranosus Biceps femoris They start at the bottom of the pelvis at a place called the ischial tuberosity. They cross the knee joint and end at the lower leg. Hamstring muscle fibers join with the tough, connective tissue of the hamstring tendons near the points where the tendons attach to bones. The hamstring muscle group helps you extend your leg straight back and bend your knee. Muscle Overload Muscle overload is the main cause of hamstring muscle strain. This can happen when the muscle is stretched beyond its capacity or challenged with a sudden load. Hamstring muscle strains often occur when the muscle lengthens as it contracts, or shortens. Although it sounds contradictory, this happens when you extend a muscle while it is weighted, or loaded. This is called an "eccentric contraction." During sprinting, the hamstring muscles contract eccentrically as the back leg is straightened and the toes are used to push off and move forward. The hamstring muscles are not only lengthened at this point in the stride, but they are also loaded — with body weight as well as the force required for forward motion. Like strains, hamstring tendon avulsions are also caused by large, sudden loads. Recovery Most people who injure their hamstrings will recover full function after completing a rehabilitation plan. Early treatment with a plan that includes the RICE protocol and physical therapy has been shown to result in better function and quicker return to sports. To prevent reinjuring your hamstring, be sure to follow your doctor's treatment plan. Return to sports only after your doctor has given you the go-ahead. Reinjuring your hamstring increases your risk of permanent damage. This can result in a chronic condition. Human Skeleton - It is composed of 270 bones at birth, but later decreases to 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. Many small supernumerary bones, such as some sesamoid bones, are not included in this count. An accessory bone or supernumerary boneis a bone that is not normally present in the body, but can be found as a variant in a significant number of people. They pose a risk of being misdiagnosed as bone fractures on radiography. In anatomy, a sesamoid bone is a bone embedded within a tendon or a muscle. It is derived from the Latin word sesamum, due to the small size of most sesamoids. Often, these bones form in response to strain, or can be present as a normal variant. The kneecap is the largest sesamoid bone in the body. Sesamoids act like pulleys, providing a smooth surface for tendons to slide over, increasing the tendon's ability to transmit muscular forces. As a human ages, some of its bones fuse, a process which typically lasts until sometime within the third decade of life. Therefore, the number of bones in an individual may be evaluated differently throughout their life. In addition, the bones of the skull and face are counted as separate bones, despite being fused naturally. Individuals may have more or fewer bones than the average (even accounting for developmental stage) owing to anatomical variations. The most common variations include sutural (wormian) bones, which are located along the sutural lines on the back of the skull, and sesamoid bones which develop within some tendons, mainly in the hands and feet. Some individuals may also have additional (i.e., supernumerary) cervical ribs or lumbar vertebrae. A fully grown adult features 26 bones in the spine, whereas a child can have 33. Cervical vertebrae (7 bones) Thoracic vertebrae (12 bones) Lumbar vertebrae (5 bones) Sacral vertebrae (5 bones at birth, fused into one after adolescence) Coccygeal vertebrae (set of 4 bones at birth; some or all fuse together, but there seems to be a disagreement between researchers as to what the most common number should be. Some say the most common is 1, others say 2 or 3, with 4 being the least likely. It is counted as 1 in this article. here are usually 26 bones in the chest but sometimes there can be additional cervical ribs in humans. Cervical ribs occur naturally in other animals such as reptiles. Hyoid (1) Sternum (1) Ribs (24, in 12 pairs) Cervical ribs are extra ribs that occur in some humans.

The muscles in the body support movement, help maintain posture, and circulate blood and other substances throughout the body. The 650 muscles are given Latin names according to location, relative size, shape, action, origin/inser-tion and/or number of origins. In an hour of reading a book, the eyes make nearly 10,000 coordinated movements. The heart is the hardest-working muscle. It pumps out 2 ounces (57 grams) of blood with every heartbeat. Daily, the heart pumps at least 2,500 gallons (9,464 liters) of blood. The heart has the ability to beat more than 3 billion times in a person’s life. Skeletal muscle fibers can be divided into two types based on how they produce and use energy: The slow-twitch muscles are efficient at using oxygen and can function over a long time before they fatigue. Fast-twitch muscles are much better at generating short bursts of strength or speed than slow-twitch muscles. Three types of muscle: Skeletal muscles control every action that a person consciously performs. Visceral or smooth muscle is found inside of organs and is controlled by the un-conscious part of the brain. Cardiac muscle is found only in the heart and is responsible for pumping blood throughout the body. How the heart works? The heart is an amazing organ. It pumps oxygen and nutrientrich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day. Your heart is a key part of your cardiovascular system, which also includes all your blood vessels that carry blood from the heart to the body and then back to the heart. How Does Blood Travel Through the Heart? As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic, muscular tubes that carry blood to every part of the body. Blood is essential. In addition to carrying fresh oxygen from the lungs and nutrients to the body's tissues, it also takes the body's waste products, including carbon dioxide, away from the tissues. This is necessary to sustain life and promote the health of all parts of the body. Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells. Termed unitary smooth muscle or visceral muscle, this type of smooth muscle is the most common observed in the human body, forming the walls of hollow organs. Cardiac Muscle Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heart’s mass. The heart beats powerfully and continuously throughout an entire lifetime without any rest, so cardiac muscle has evolved to have incredibly high contractile strength and endurance. And because the heart maintains its own rhythm, cardiac muscle has developed the ability to quickly spread electrochemical signals so that all of the cells in the heart can contract together as a team. Cardiac muscle tissue is made up of many interlocking cardiac muscle cells, or fibers, that give the tissue its properties. Each cardiac muscle fiber contains a single nucleus and is striated, or striped, because it appears to have light and dark bands when seen through a microscope. The dark bands represent areas of thick protein filaments made of myosin proteins that block light passing through the cell and appear dark. Between the dark bands are thin filaments made of actin protein that allow light to pass through and appear light. When the muscle fibers contract, myosin pulls the actin filaments together like an accordion to shrink the muscle cell and make it contract. While each cell is not very strong by itself, millions of cardiac muscle cells working together are easily able to pump all of the blood in the body through the heart in less than a minute. Cardiac muscle cells have a branched shape so that each cell is in contact with three of four other cardiac muscle cells. Together all of the cardiac muscle cells in the heart form a giant network connected end to end. At the ends of each cell is a region of overlapping, finger-like extensions of the cell membrane known as intercalated disks. The intercalated disks form tight junctions between the cells so that they cannot separate under the strain of pumping blood and so that electrochemical signals can be passed quickly from cells to cell. The passage of signals from cell to cell allows cardiac muscle tissue to contract very quickly in a wave-like pattern to effectively pump blood throughout the body. Another feature that is unique to cardiac muscle tissue is autorhythmicity. Cardiac muscle tissue is able to set its own contraction rhythm due to the presence of pacemaker cells that stimulate the other cardiac muscle cells. The pacemaker cells normally receive inputs from the nervous system to increase or decrease the heart rate depending on the body’s needs. However, in the absence of nervous system stimulation, the pacemaker cells can produce a regular heart rhythm. Did you know you have more than 600 muscles in your body? They do everything from pumping blood throughout your body to helping you lift your heavy backpack. You control some of your muscles, while others — like your heart — do their jobs without you thinking about them at all. Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle. You have three different types body: smooth muscle, cardiac (say: KAR-dee-ak) SKEL-uh-tul) muscle. of muscles in your muscle, and skeletal (say: Smooth Muscles Smooth muscles — sometimes also called involuntary muscles — are usually in sheets, or layers, with one layer of muscle behind the other. You can't control this type of muscle. Your brain and body tell these muscles what to do without you even thinking about it. You can't use your smooth muscles to make a muscle in your arm or jump into the air. But smooth muscles are at work all over your body. In your stomach and digestive system, they contract (tighten up) and relax to allow food to make its journey through the body. Your smooth muscles come in handy if you're sick and you need to throw up. The muscles push the food back out of the stomach so it comes up through the esophagus(say: ih-SAH-fuh-gus) and out of the mouth. Smooth muscles are also found in your bladder. When they're relaxed, they allow you to hold in urine (pee) until you can get to the bathroom. Then they contract so that you can push the urine out. These muscles are also in a woman's uterus, which is where a baby develops. There they help to push the baby out of the mother's body when it's time to be born. You'll find smooth muscles at work behind the scenes in your eyes, too. These muscles keep the eyes focused. A Hearty Muscle The muscle that makes up the heart is called cardiac muscle. It is also known as the myocardium (say: my-uh-KAR-dee-um). The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body. Just like smooth muscle, cardiac muscle works all by itself with no help from you. A special group of cells within the heart are known as the pacemaker of the heart because it controls the heartbeat. Skeletal Muscle Now, let's talk about the kind of muscle you think of when we say "muscle" — the ones that show how strong you are and let you boot a soccer ball into the goal. These are your skeletal muscles — sometimes called striated (say: STRY-aytud) muscle because the light and dark parts of the muscle fibers make them look striped (striated is a fancy word meaning striped). Skeletal muscles are voluntary muscles, which means you can control what they do. Your leg won't bend to kick the soccer ball unless you want it to. These muscles help to make up the musculoskeletal (say: mus-kyuh-lowSKEL-uh-tul) system — the combination of your muscles and your skeleton, or bones. Together, the skeletal muscles work with your bones to give your body power and strength. In most cases, a skeletal muscle is attached to one end of a bone. It stretches all the way across a joint (the place where two bones meet) and then attaches again to another bone. Skeletal muscles are held to the bones with the help of tendons (say: TENdunz). Tendons are cords made of tough tissue, and they work as special connector pieces between bone and muscle. The tendons are attached so well that when you contract one of your muscles, the tendon and bone move along with it. Skeletal muscles come in many different sizes and shapes to allow them to do many types of jobs. Some of your biggest and most powerful muscles are in your back, near your spine. These muscles help keep you upright and standing tall. They also give your body the power it needs to lift and push things. Muscles in your neck and the top part of your back aren't as large, but they are capable of some pretty amazing things: Try rotating your head around, back and forth, and up and down to feel the power of the muscles in your neck. These muscles also hold your head high. Face Muscles You may not think of it as a muscular body part, but your face has plenty of muscles. You can check them out next time you look in the mirror. Facial muscles don't all attach directly to bone like they do in the rest of the body. Instead, many of them attach under the skin. This allows you to contract your facial muscles just a tiny bit and make dozens of different kinds of faces. Even the smallest movement can turn a smile into a frown. You can raise your eyebrow to look surprised or wiggle your nose. And while you're looking at your face, don't pass over your tongue — a muscle that's attached only at one end! Your tongue is actually made of a group of muscles that work together to allow you to talk and help you chew food. Stick out your tongue and wiggle it around to see those muscles at work. Major Muscles Because there are so many skeletal muscles in your body, we can't list them all here. But here are a few of the major ones: In each of your shoulders is a deltoid (say: DEL-toyd) muscle. Your deltoid muscles help you move your shoulders every which way — from swinging a softball bat to shrugging your shoulders when you're not sure of an answer. The pectoralis (say: pek-tuh-RAH-lus) muscles are found on each side of your upper chest. These are usually called pectorals (say: PEK-tuh-rulz), or pecs, for short. When many boys hit puberty, their pectoral muscles become larger. Many athletes and bodybuilders have large pecs, too. Below these pectorals, down under your ribcage, are your rectus abdominus(say: REK-tus ab-DAHM-uh-nus) muscles, or abdominals (say: ab-DAHM-uh-nulz). They're often called abs for short. When you make a muscle in your arm, you tense your biceps (say: BYE-seps) muscle. When you contract your biceps muscle, you can actually see it push up under your skin. Your quadriceps (say: KWAD-ruh-seps), or quads, are the muscles on the front of your thighs. Many people who run, bike, or play sports develop large, strong quads. And when it's time for you to take a seat? You'll be sitting on your gluteus maximus (say: GLOOT-ee-us MAK-suh-mus), the muscle that's under the skin and fat in your behind! The sense of space In addition to the traditional big five, there is another sense that deals with how your brain understands where your body is in space. This sense is called proprioception. Proprioception includes the sense of movement and position of our limbs and muscles. For example, proprioception enables a person to touch their finger to the tip of their nose, even with their eyes closed. It enables a person to climb steps without looking at each one. People with poor proprioception may be clumsy and uncoordinated. Researchers at the National Institutes of Health (NIH) found that people who have particularly poor proprioception through mechanosensation — the ability to sense force, such as feeling when someone presses down on your skin — may have a mutated gene that is passed down from generation to generation. That comes from a September 2016 study in the New England Journal of Medicine. "The patient's version of [the gene] PIEZO2 may not work, so their neurons cannot detect touch or limb movements," Alexander Chesler, a principal investigator at the National Center for Complementary and Integrative Health and the lead author of the study, said in a statement. Additional senses & variations There are more-subtle senses that most people never really perceive. For example, there are neuron sensors that sense movement to control balance and the tilt of the head. Specific kinesthetic receptors exist for detecting stretching in muscles and tendons, helping people to keep track of their limbs. Other receptors detect levels of oxygen in certain arteries of the bloodstream. Sometimes, people don't even perceive senses the same way. People with synesthesia can see sounds as colors or associate certain sights with smells, for example. Is intelligence an acquired trait or hereditary? Everything Physical is hereditary. It is inherited by our parents (or rather from our parents genes). And these genes are modified (Mutation) over a period of time, that's what Evolution is. If a mother (or rather parents) is physically strong, then it is very likely that it's children will be Physically strong (only when they born) compared to the children from a mother who is not physically very strong. After they are born, then it depends on the children how able they are to maintains those good mutation. (like physical strength developed by their parents) If they don't work physically that hard, then obviously they won't remain strong, but if the other weak children work really hard physically and get good diet as well, they can become physically much stronger to the other ones. Well, the same applies to intelligence as well. Everyone of us is born with some hereditary intelligence. (like cells in our brain, some of us have weak and some of have strong). But, later if we work hard and give good exercise to brain, we can definitely improve them and gain some other ideas (may be some nerve cells (or most of them) in the brain are quite idle and gets activated when we learn something and they remain idle for some smart guys who does not learn that thing). So, most of the intelligence we gain, is acquired. Cutting the writs This happens because there is a major artery in the wrists, and it can be felt and seen. It is where the pulse is taken ona wrist. If this artery is cut, because it is so large and a vital area for blood flow, the loss of blood will surely cause a person to bleed to death in a very short amount of time. The human body only contains 4 quarts of blood, so if your artery is punctured you will easily loose most of that blood, too quickly for an infusion to replace it. Therefore, you will die within a couple minutes. Cutting a wrist” does not always result in death. But, when death does result, it is because the wound is cut deeply enough to sever the radial artery; the artery which is typically used to take one’s pulse. (There is also an ulnar artery, but it is deeper, and not as easily located or injured.) When the artery is severed it will begin to bleed profusely. If the cutting is deep enough, and extends to the full width of the ulnar aspect of the wrist, it is possible that the ulnar artery could also be lacerated, but that is not usually the case (except in the most violent type of injury) in suicide victims. If bleeding of the radial artery is not abated, enough blood will eventually be lost to cause the heart to cease beating. At that point, death will occur. Adam’s apple: Sex difference. An Adam's apple is usually a feature of adult males, because its size in males tends to increase considerably during puberty. However, somewomen also have an Adam's apple. Its developmentis considered a secondary sexual characteristic of males that appears as a result of hormonal activity Extra fingers or toes: Polydactyly is a condition where someone is born with one or more extra fingers or toes. It can occur on one or both hands or feet. The name comes from the Greek poly (many) and dactylos (finger). The extra fingers or toes are described as "supernumerary," which means "more than the normal number." For this reason, the condition is sometimes called supernumerary digit. A range of treatments is available depending on the type of polydactyly, and the cause is often genetic. Causes Polydactyly may be passed down in families. When polydactyly is passed down, it is known as familial polydactyly. This form of polydactyly typically happens in isolation, meaning a person may not experience any associated symptoms. Polydactyly may also be associated with a genetic condition or syndrome, which means it may be passed down along with a genetic condition. If polydactyly is not passed down, it occurs due to a change in a baby's genes while it is in the womb Introduction to the urinary system The urinary system consists of all the organs involved in the formation and release of urine. It includes the kidneys, ureters, bladder and urethra. The kidneys are bean-shaped organs which help the body produce urine to get rid of unwanted waste substances. When urine is formed, tubes called ureters transport it to the urinary bladder, where it is stored and excreted via the urethra. The kidneys are also important in controlling our blood pressureand producing red blood cells. How might removal of one or both testicles affect a man’s sex life? An orchidectomy is a surgical procedure that involves the removal of one or both testicles. There are several reasons why a man might have this operation, such as cancer, injury, or trauma to the area. Regardless of the reason, the effects of this surgery on a man’s sex life depend on the number of testicles removed. When one testicle is removed, there is usually no effect on a man’s sexual function. Most of the time, the remaining testicle produces enough testosterone and sperm to compensate for the testicle that has been removed. Therefore, the man should still be able to get an erection and ejaculate as he did before. He should also be able to father biological children. Removal of both testicles does affect a man’s sexual function. In this case, his body cannot produce testosterone. Without this hormone, a man’s libido can decrease and it might be difficult for him to have erections. However, testosterone replacement therapy can help restore sexual function. (Click here to learn more about low testosterone and testosterone replacement therapy.) Men who have both testicles removed also become infertile, as the body is no longer able to make sperm. Many men decide to bank sperm before surgery so that they may father biological children in the future, if they wish. In addition to the physical aspects of sexual function, removal of one or both testicles can have some psychological and emotional effects as well. Some men develop body image issues because their genitals no longer look the same. (Some choose to have a testicular prosthesis – a false testis made of silicone – implanted at the time of surgery.) Men who have had one or both testicles removed might also feel less masculine or anxious about how a sexual partner will react. These feelings can affect sexuality, too. Open, honest communication can help alleviate some of these anxieties. Men who need more help may benefit from seeing a counselor or sex therapist. Next question: Why might a man need to have one or both testicles removed? What Does the Bible Say About Dreams? I have been dreaming a lot about being in water, feeling water flowing in my heart. What is happening to me? My answer will not necessarily be concerned with the scientific study of dreams, but will focus on the Biblical foundation for the definition of a dream, the cause of a dream, the reality of dreams, some common purposes for dreams and the connection or lack of connection between dreams in the Bible and dreams today. The Definition of a Dream Once again I want to emphasize that we will define a dream using the scriptural definition. We often speak of day dreaming or following our dreams in addition to our standard concept of dreaming, but here we will focus on the dreams that we have during sleep. The Bible defines a dream in Job 33:15 , "In a dream, in a vision of the night, when deep sleep falleth upon men, in slumberings upon the bed;". The Bible says several things in this one verse. First of all, a dream is a vision of the night. The verse also teaches that a dream occurs when deep sleep falls upon men. According to the Bible, a vision is something that occurs when a man is awake, while a dream is something that occurs when a man is asleep. Some who study dreams say that we are always dreaming when we sleep, but we only remember the dreams right before we awake. This would actually fit with the scriptures in several cases where men remember a dream that actually woke them up. The Cause of a Dream From everything that I have read about dreams, it seems as though we still do not have solid answers as to what causes them. The Bible, however, does contain a verse that quite possibly gives us the cause. Consider Ecclesiastes 5:3 , "For a dream cometh through the multitude of business; and a fool's voice is known by multitude of words." Now it is interesting that several who study dreams suggest that when your body slows down to rest, your mind continues to work. The Bible says that the multitude of business will cause dreams. This could be the multitude of physical and emotional business or it could be the multitude of mental business, but either way it appears that this is what causes us to dream. Though your body settles in rest, your mind can keep right on working and thinking. The Reality of Dreams Dreams can appear to be very real. Sometimes you wake up scared, sometimes mad and sometimes sad, yet you realize after a while that it was just a dream and you settle down. The Bible speaks of this in Isaiah 29:8 when it says, "It shall even be as when an hungry man dreameth, and, behold, he eateth; but he awaketh, and his soul is empty: or as when a thirsty man dreameth, and, behold, he drinketh; but he awaketh, and, behold, he is faint, and his soul hath appetite". You may dream of eating or drinking, but when you awake you are still empty. It may have appeared real, but it was not. Something else to consider here is that dreams are not necessarily supposed to mean anything. Consider Ecclesiastes : 5:7 "For in the multitude of dreams and many words there are also divers vanities: but fear thou God." This verse tells us that a multitude of dreams can be worth absolutely nothing. We are not to trust in them, however real they seem; we are rather to fear God. Common Purposes for Dreams In the Bible, especially the Old Testament, the Lord used dreams for various reasons. We will not state all of them, but will give you a few to consider. 1. There were times when God used a dream to give a warning. Consider the twelfth verse of Matthew 2 where the Bible says, "And being warned of God in a dream that they should not return to Herod, they departed into their own country another way." The Lord appeared to the wise men here for the purpose of warning them not to return to Herod, but to go back home another way. In the very next verse Joseph is also warned of the Lord in a dream to flee into Egypt with the Lord Jesus. The very first dream that I have seen in the scripture is when God spoke to Abimelech and warned him that he had taken another man's wife. Obviously this is a common purpose of dreams within the context of scripture. 2. There were times when God used a dream to reveal prophecy. Joseph was a man subject to dreams and the interpretation of dreams. In Genesis 37, Joseph dreamed a dream about his brethren bowing down to him. If you know the story of Joseph, you know that the dreams are the only evidence of this occuring until he was promoted to the second in command under Pharaoh. For approximately 13 years he had nothing else but these dreams that told of the future. If you are familiar with the Book of Daniel, you will remember that Nebuchadnezzar dreamed dreams that have a tremendous amount of prophecy in them. There are other dreams in the Bible that I would consider to fall into this category as well. 3. There were times when God used a dream to encourage. I would have to say that this is nowhere near as common as the first two, but I do believe there is an instance that could be construed as a dream for the purpose of encouraging obedience to the Lord. In Judges chapter 7, we find the Lord thinning out the army of Gideon before he goes to battle with the vast army of Midian. Gideon begins with 32,000 soldiers. In verse 3, we find that 22,000 went home because of fear and in verse 6, we find that 9,700 went home because of the way they drank water. This left Gideon with an army of only 300 soldiers. In this same chapter the Lord instructed Gideon that if he was afraid he should go down unto the host and then he would be strengthened. When Gideon arrived in the host, he heard a man telling a dream to another man. The interpretation of the dream just so happened to be that the army of Gideon was going to defeat the Midianites. Immediately upon hearing of this dream, Gideon was strengthened and he worshipped God. Surely the whole purpose for this man's dream was the encouragement of Gideon. Dreams of the Bible and Dreams Today Now here is where people will begin to split from me and call me a heretic and all sorts of other things. I personally believe that God does not speak to men through dreams and visions today as He did in the Bible. Consider some things with me. First of all, God used dreams in the Bible to warn men of sin and wrong, but today we have His completed word that will keep us from sin. As a matter of fact the Psalmist said, "Thy word have I hid in mine heart, that I might not sin against thee." Something else to consider is that dreams were often for the purpose of revealing prophecy, yet we have in the word of God the revelation of the future events that God wants to make known to men. Another point to consider is Joel's reference to prophesy, dreams and visions. In Joel 2:28 he says, "And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:". Now this verse is quoted as coming to pass in Acts 2:17 , yet any honest student of the Bible knows that 1.) not all of what Joel said was fulfilled on Pentecost and 2.) the signs and wonders that were associated with the age of the apostles were for the Jews and went out of business during the ministry of the apostle Paul. Yet Joel still prophesied that dreams will again be a means whereby God speaks to men, but in the context of Joel 2 it is easily understood that this will occur during the time of the tribulation. Now, let me clarify something on the other end of this argument. I very strongly believe that God can and will allow people to have dreams that could turn them to Him. For example, I believe God would allow a man to have a dream about hell, if it would keep him from going there. I just don't believe that we can give our dreams the weight that we can give to Bible dreams. Ultimately when we dream and it causes us concern, we ought to go to God and ask Him if He is trying to teach us something. If the Lord does not burn it into your heart that He is trying to teach you something then chalk it up to a multitude of business and go on about your day. Freud (1915) described conscious mind, which consists of all the mental processes of which we are aware, and this is seen as the tip of the iceberg. For example, you may be feeling thirsty at this moment and decide to get a drink. The preconscious contains thoughts and feelings that a person is not currently aware of, but which can easily be brought to consciousness (1924). It exists just below the level of consciousness, before the unconscious mind. The preconscious is like a mental waiting room, in which thoughts remain until they 'succeed in attracting the eye of the conscious' (Freud, 1924, p. 306). This is what we mean in our everyday usage of the word available memory. For example, you are presently not thinking about your mobile telephone number, but now it is mentioned you can recall it with ease. Mild emotional experiences may be in the preconscious but sometimes traumatic and powerful negative emotions are repressed and hence not available in the preconscious. Finally, the unconscious mind comprises mental processes that are inaccessible to consciousness but that influence judgements, feelings, or behavior (Wilson, 2002). According to Freud (1915), the unconscious mind is the primary source of human behavior. Like an iceberg, the most important part of the mind is the part you cannot see. Our feelings, motives and decisions are actually powerfully influenced by our past experiences, and stored in the unconscious. Freud applied these three systems to his structure of the personality, or psyche – the id, ego and superego. Here the id is regarded as entirely unconscious whilst the ego and superego have conscious, preconscious, and unconscious aspect. Unconscious Mind While we are fully aware of what is going on in the conscious mind, we have no idea of what information is stored in the unconscious mind. The unconscious contains all sorts of significant and disturbing material which we need to keep out of awareness because they are too threatening to acknowledge fully. The unconscious mind acts as a repository, a ‘cauldron’ of primitive wishes and impulse kept at bay and mediated by the preconscious area. For example, Freud (1915) found that some events and desires were often too frightening or painful for his patients to acknowledge, and believed such information was locked away in the unconscious mind. This can happen through the process of repression. The unconscious mind contains our biologically based instincts (eros and thanatos) for the primitive urges for sex and aggression (Freud, 1915). Freud argued that our primitive urges often do not reach consciousness because they are unacceptable to our rational, conscious selves. People has developed a range of defence mechanisms (such as repression) to avoid knowing what their unconscious motives and feelings are. Freud (1915) emphasized the importance of the unconscious mind, and a primary assumption of Freudian theory is that the unconscious mind governs behavior to a greater degree than people suspect. Indeed, the goal of psychoanalysis is to reveal the use of such defence mechanisms and thus make the unconscious conscious. Freud believed that the influences of the unconscious reveal themselves in a variety of ways, including dreams, and in slips of the tongue, now popularly known as 'Freudian slips'. Freud (1920) gave an example of such a slip when a British Member of Parliament referred to a colleague with whom he was irritated as 'the honorable member from Hell' instead of from Hull. Critical Evaluation Initially, psychology was sceptical regarding the idea of mental processes operating at an unconscious level. To other psychologists determined to be scientific in their approach (e.g. behaviorists) the concept of the unconscious mind has proved a source of considerable frustration because it defies objective description, and is extremely difficult to objectively test or measure. However, the gap between psychology and psychoanalysis has narrowed, and the notion of the unconscious is now an important focus of psychology. For example, cognitive psychologyhas identified unconscious processes, such as procedural memory (Tulving, 1972), automatic processing (Bargh & Chartrand, 1999; Stroop, 1935), and social psychology has shown the importance of implicit processing (Greenwald & Banaji, 1995). Such empirical findings have demonstrated the role of unconscious processes in human behavior. However, empirical research in psychology has revealed the limits of the Freudian theory of the unconscious mind, and the modern notion of an 'adaptive unconscious' (Wilson, 2004) is not the same as the psychoanalytic one. Indeed, Freud (1915) has underestimated the importance of the unconscious, and in terms of the iceberg analogy there is a much larger portion of the mind under the water. The mind operates most efficiently by relegating a significant degree of high level, sophisticated processing to the unconscious. Whereas Freud (1915) viewed the unconscious as a single entity, psychology now understands the mind to comprise a collection of modules that has evolved over time and operate outside of consciousness. For example, universal grammar (Chomsky, 1972) is an unconscious language processor that lets us decide whether a sentence is correctly formed. Separate to this module is our ability to recognize faces quickly and efficiently, thus illustrating how unconscious modules operate independently. Finally, while Freud believed that primitive urges remained unconscious to protect individuals from experiencing anxiety, the modern view of the adaptive unconscious is that most information processing resides outside of consciousness for reasons of efficiency, rather than repression (Wilson, 2004). THE UNCONSCIOUS MIND IN CHRISTIAN THEOLOGY In medicine especially in psychoanalysis, we talk a lot about the unconscious mind and the influences it exerts on our lives. As you may already know, our minds can be divided into the conscious and unconscious mind. A lot of my readers care about their spiritual or inner life and some wonder how the unconscious is viewed in popular religious traditions like Christianity, Islam, Buddhism etc. Today, I will focus only on the view of the unconscious in Christian theology by letting us hear from what two esteemed Christian theologians have to say about it. Dr. John Piper’s views on the unconscious Dr. John Piper, renown theologian and pastor, said this: “I would say probably 99 percent of our lives is lived without immediate reflection upon a life principle. Rather, we just act. If you think about your day there are maybe a hundred big decisions you make in a day. And by ‘big’ I just mean ‘conscious.’ But right now, I am just talking to you. I am just choosing words. Before every word, I am not stopping and saying, “Now, what principle is going to govern this word, and what principle is going to govern this sentence?” They are just kind of tumbling out of me right now. Well, that is scary. Right? Where did they come from? Most of our lives are lived spontaneously. Most of our lives are not lived after ten seconds of reflection on a biblical principle. So where do they come from? They come from being a kind of person. And that raises the question, how do you become a kind of person so that you are a good tree that bears spontaneous good fruit instead of a bad tree that bears spontaneously bad fruit? And the answer is you soak in the Scriptures and you let your sight of Jesus and your taste of Jesus and his ways in the Bible affect and shape your soul. Your soul marinates in the sauces of grace until the soul is made soft and tender and supple and sensitive to the leadings of the Holy Spirit so that in a kind of spontaneous way, it responds. Jesus said we will be called to account for every idle word that we speak. Now, idle words are words spoken before you have a chance to think on any biblical principle that you have gotten from your text in the morning. So I think people who are bent on trying to get three principles or three points or something and then try consciously to follow them during the day are trying to do something impossible that we were never designed to do. I would put it like this. A godly life is lived out of a heart that is just astonished at grace — “Amazing grace, how sweet the sound that saved a wretch like me.” So we go to the Bible to be astonished. We go to the Bible to be amazed at God and amazed at Christ and amazed at the cross and amazed at grace and amazed at the gospel. And when we are stunned and amazed and humbled, we walk out of our study or our chair or wherever we are having devotions, and there is a spirit and a flavor about us that makes us a better person at the kitchen table and when we go to work. All that just to say I am not opposed to principles. Good night, I write books in which I am trying to do things so they are helpful to meditate on. But that is the key: meditating on truth shapes the soul. 2 Corinthians 3:18 says that we become what we behold. So my goal in reading the Bible is mainly to become a kind of person. Don’t amass a long list.” At this point, the interviewer interjects and asks Piper a clarifying question: Pastor John, do you think it is appropriate to talk about the subconscious here? Is it right to say we live out the Christian life through an informed, Spirit-filled subconscious? Yes. That is basically what I was trying to say, that most of our life is lived from resources that are not presently reflected on in our mind. Our words are coming from inside — “What comes out of the mouth proceeds from the heart, and this defiles a person” (Matthew 15:18). And most of that heart is unconscious or subconscious and that is shaped day by day by what we are taking in. It is shaped by what we do with our eyes on the computer, and it is especially shaped by what we do with our Bibles and our prayer. Whenever I pray I am pleading with God, “Work down deeper than I can get in my reading right now. Take your scalpel, and don’t just deal with the sins I am aware of: go be a surgeon.” Surgeons put you to sleep, and they go into places on your body you don’t know anything about and work on you. That is what God has to do with us. So, yes I think the subconscious is being worked on by the Holy Spirit all the time. Dr. Dallas Willard’s views on the unconscious The late renowned professor of philosophy at the University of Southern California, Dallas Willard, –himself also a Christian theologian and minister–argued that the soul is the total person. In other words, a soul is a complete human being and is made up of 4 major distinct but interconnected parts: The body, mind, spirit, and social connectedness. In his book, Renovation of the Heart, Now, right on the conscious surface of our “world within” lie some of our thoughts, feelings, intentions, and plans. These are the ones we are aware of. They may be fairly obvious to others as well as to ourselves. In terms of them, we consciously approach our world and our actions within it. But these surface aspects are also a good indication of the general nature of the unconscious “spiritual depth within,” of what sorts of things make it up. But the thoughts, feelings, and intentions we are aware of are, after all, only a small part of the ones that are really there in our depths; and they often are not the ones most revealing of who we actually are and why we do what we do. What we really think, how we really feel, and what we really would do in circumstances foreseen and unforeseen may be totally unknown to ourselves or to others familiar with us. We may pass one another–even pass ourselves, if you can image that–like “ships in the night.” We do it all the time. Christian theology is clear about the existence of the unconscious and the significant part it plays in influencing our lives. Jesus Christ went so far as to say our hearts reflect who we really are. You are a good person if you have a good heart and an evil person if you have an evil heart. “No good tree bears bad fruit, nor does a bad tree bear good fruit. Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.” Jesus Christ. The heart as Jesus uses it and is Christian theology uses it is not limited to the conscious mind alone but actually mostly the unconscious mind. The word “kardia” is translated to mean the heart; mind, character, inner self, will, intention, center. It means the “seat and center of all physical and spiritual life and the vigor and sense of physical life.” It is also presented as the “seat of the thoughts, passions, desires, appetites, affections, purposes, endeavors” In Christian theology, meditating on truth is how one renews the mind (conscious and unconscious) and develops the right perspective or paradigms for interpreting life. Bone Diseases he human body contains 206 bones. Bones are living tissue, just like all the other parts of our bodies and, as such, are constantly going through a cycle of renewal. Older bone tissue is replaced with newly formed bone tissue in a process called remodeling. Much like the remodeling of a home, our skeletal structure is reinforced so that we can depend on it throughout our lives. We commonly measure the condition of our bones by its density or “bone mass.” A bone mineral density (BMD) screening, for example, can help a physician identify the calcium content of bones – and thus how strong our bones are. Our bone density peaks when we are young adults, typically between the ages of 25 and 30. Thereafter, as we continue to age, our bones gradually lose density. But there are ways to combat this natural loss of bone mass – such as vitamins and minerals, medications like estrogen replacement therapy, and strength-training and weight-bearing exercises. So, what are the most common diseases or disorders that affect the bones? Here are 10 you’ll want to avoid if possible: 1. Osteoporosis: Osteoporosis, in which low density means the bones are brittle and weak and prone to easily break, is by far the most common bone disease. It currently affects 44 million – or approximately half of all – Americans aged 50 and older. Osteoporosis strikes more women than men, and even children may be at risk of developing juvenile osteoporosis. Bone density problems may occur because the body loses too much bone tissue, makes too little of it, or some combination of both. It tends to be symptomless. That is, people with osteoporosis tend not to know they have it – until a bone fracture has them visiting a doctor who makes the diagnosis. 2. Paget’s Disease: This is a bone disorder where the bone renewal process (remodeling) occurs too quickly, leading to bone deformities (soft, enlarged bones such as of the spine, pelvis, skull, and the long bones of the thighs and lower leg). Paget’s disease tends to occur in white adults over the age of 55 and may have a hereditary component. 3. Bone Infection: Also called osteomyelitis, infection of bone tissue is a rare but serious condition. It can occur following a surgery, such as a hip replacement, or may spread to the bones from another part of the body. Pain, swelling, and redness are common symptoms of a bone infection, and antibiotics are a common component of treatment. In some cases, portions of the infected bone may need to be surgically removed. 4. Osteonecrosis: Without blood, bone tissue dies, a disease called osteonecrosis. In most cases, it occurs as the result of trauma to the bone that disrupts blood flow to the bone – such as a hip fracture. Prolonged high-dose steroid use can also cause this type of bone cell death. Once the bone tissue dies, the bone weakens and collapses. Pain that gradually gets worse may indicate osteonecrosis. 5. Bone Tumors: Bone tumors occur when the uncontrolled growth of cells occurs inside bone. These tumors can be benign or malignant, although benign (noncancerous) bone tumors that do not impinge on other bone tissue and do not spread are more common. 6. Osteoarthritis: A chronic degenerative joint disease, osteoarthritis is the most common type of arthritis, with more than 3 million Americans diagnosed each year. Osteoarthritis occurs when the cartilage that acts as a cushion between bones breaks down and the bones rub together, causing pain, inflammation, and stiffness. 7. Rheumatoid Arthritis: Rheumatoid arthritis is a chronic, immunodeficiency disorder in which the immune system mistakenly attacks the body’s tissues, such as the joints in the hands and feet. Unlike the wear-and-tear damage that occurs with osteoarthritis, RA affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. 8. Scoliosis: This condition, in which the bones of the spine curve abnormally to the left or right, usually strikes just prior to puberty. There are approximately 3 million scoliosis diagnosis made each year in the US, although most cases are mild. In some cases, the spinal deformities get worse with time. Its cause is unknown, although a hereditary component is suspected. 10.Low Bone Density: Also called osteopenia, it is diagnosed when a person’s bone density is lower than it should be. Low bone density can lead to osteoporosis, which causes fractures, pain, and a stooped appearance. It is important to make the changes necessary to improve bone density if you are diagnosed with osteopenia. 11.Gout: The joints are unusually affected in people who develop gout, a common disorder in which excess uric acid crystals accumulate in the joints, causing abnormal swelling, pain, and redness. The big toe is typically noticeably swollen, but symptoms may also occur in other joints, including the ankle, foot, or knee. Gout may occur due to your diet, or if your kidneys are not properly processing uric acid. GO What Causes Kyphosis? Kyphosis, also known as roundback or hunchback, is a condition in which the spine in the upper back has an excessive curvature. The upper back, or thoracic region of the spine, is supposed to have a slight natural curve. The spine naturally curves in the neck, upper back, and lower back to help absorb shock and support the weight of the head. Kyphosis occurs when this natural arch is larger than normal. If you have kyphosis, you may have a visible hump on your upper back. From the side, your upper back may be noticeably rounded or protruding. In addition, people with hunchback appear to be slouching and have noticeable rounding of the shoulders. Kyphosis can lead to excess pressure on the spine, causing pain. It may also cause breathing difficulties due to pressure put on the lungs. Kyphosis in elderly women is known as dowager’s hump. Common causes of kyphosis Kyphosis can affect people of any age. It rarely occurs in newborns because it’s usually caused by poor posture. Kyphosis caused by poor posture is called postural kyphosis. When to seek treatment for kyphosis You should seek treatment if your kyphosis is accompanied by: pain breathing difficulties fatigue Much of our bodily movement depends on the health of the spine, including our: flexibility mobility activity Getting treatment to help correct the curvature of your spine may help you reduce the risk of complications later in life, including arthritis and back pain. Treating kyphosis Treatment for kyphosis will depend on its severity and underlying cause. Here are some of the more common causes and treatments: Scheuermann’s disease: A child may receive physical therapy, braces, or corrective surgery. Infection: Your doctor will probably prescribe antibiotics for you. Tumors: Typically, tumors are only removed if there’s concern for spinal cord compression. If this is present, the surgeon may try to remove the tumor, but frequently this destabilizes the bone. In such cases, a spinal fusion is often also necessary. Osteoporosis: It’s essential to treat bone deterioration to prevent kyphosis from worsening. Poor posture: You will not need aggressive treatments. Risks of untreated kyphosis For most people, kyphosis does not cause serious health problems. This is dependent on the cause of the kyphosis. If kyphosis is caused by poor posture, you may suffer from pain and breathing difficulties. These will only get worse later in life. You can treat kyphosis early by: strengthening the muscles of the back seeing a physical therapist Your goal will be to improve your posture long-term to decrease pain and other symptoms.
