Anatomy (dissect/cut) – structure; Physiology – function 2 basic approaches to the study of Anatomy: 1. Systemic Anatomy – study of body by systems (Skeletal) 2. Regional Anatomy – study of the organization of the body by areas. (Head, abdomen) 2 ways to examine the internal structures of a living person: 1. Surface Anatomy – study of external features (bony projections) 2. Anatomical imaging – x-rays, ultrasound, MRI, etc. Structural Levels: (CCTOOO) 1. Chemical Level – atoms combine to form molecules. 2. Cell Level – molecules form organelles such as the nucleus and mitochondria, which make up cells. 3. Tissue Level –similar cells and the materials surrounding them (CEMN) 4. Organ Level – Different tissues combine to form organs. Ex. Kidneys 5. Organ System Level – group of organs classified as a unit because of a common function or set of functions. Ex. Urinary system 6. Organism Level – organ system makes up an organism; any living thing considered as a whole. Ex. Bacterium, human Characteristics of Life: (OMRGDR) 1. Organization – specific relationship of many individual parts of an organism, interacting and working together. Disruption can result in loss of function and death. 2. Metabolism – ability to use energy to perform vital functions. 3. Responsiveness – ability of an organism to sense changes in the environment and make the adjustments that help maintain its life. Ex. Body temp increases, produces sweat 4. Growth – increase in size of all or part of the organism. 5. Development – changes an organism undergoes through time. Differentiation – change in cell structure and function from generalized to specialized. 6. Reproduction – formation of new cells or new organisms. Homeostasis – maintenance of a relatively constant environment within the body despite fluctuations in external/internal environment. Homeostatic Mechanisms – sweating, shivering Organ Systems of the Body: (MINCES, LURR2D) 1. Muscular – produces body movements, maintains posture, produces body heat. 2. Integumentary – provides protection, regulates temperature, prevents water, helps produce vitamin D 3. Nervous – major regulatory system, detects sensation & controls movements, physiological processes, intellectual functions. 4. Cardiovascular – transports nutrients, waste products, gases, and hormones throughout the body. Plays a role in the immune response & regulation of body temperature. 5. Endocrine – major regulatory system, influences metabolism, growth, reproduction 6. Skeletal – provides protection & support, allows body movements, produces blood cells, stores minerals and adipose tissue. 7. Lymphatic – removes foreign substances from the blood & lymph, combats disease, maintains tissue fluid balance, absorbs dietary fats from the digestive tract. 8. Urinary – removes waste products from the blood & regulates blood pH, ion balance, water balance. 9. Respiratory – exchanges O & CO2 between blood and air, regulates blood pH. Normal: 7.35 – 7.45 10. Female Reproductive – produces oocytes, site of fertilization, fetal development, produces milk, hormones that influence sexual function & behavior. 11. Male Reproductive – produces and transfers sperm cells to the female. 12. Digestive – performs mechanical & chemical digestion, absorption of nutrients, elimination of wastes. Negative-Feedback Mechanisms – maintain homeostasis “decreases”. Positive-Feedback Mechanisms – “increases” Components of Negative-Feedback: (RCE) 1. Receptor – monitors the value of a variable, ex. body temp 2. Control Center – determines the set point for the variable & receives input from the receptor about the variable ex. Part of the brain 3. Effector – ex. sweat glands, can change the value of the variable when directed by the control center. Anatomical position – person standing upright with the face directed forward, upper limbs hanging to the side, and the palms are facing forward. Supine – lying face upward; Prone – lying face downward Superior/Cephalic – up, above; Inferior/Caudal – down/below Anterior/Ventral – front, belly; Posterior/Dorsal – back Proximal – nearest; Distal – distant Medial – midline; Lateral – away from midline Superficial – structure close to the surface of body Deep – toward the interior of the body. Frontal – forehead; Orbital – eye; Nasal – nose Oral – mouth; Cervical – neck; Otic – ear; Buccal – cheek Mental – chin; Clavicular – collarbone; Axillary – armpit Brachial – arm; Antecubital – front of elbow Antebrachial – forearm; Carpal – wrist; Palmar – palm Digital – fingers; Pectoral – chest; Sternal – breastbone Mammary – breast; Abdominal – abdomen Umbilical – navel; Pelvic – pelvis; Inguinal – groin; Pubic – genital; Coxal – hip; Femoral – thigh; Patellar – knee cap; Crural – leg; Talus – ankle; Dorsum – top of foot; Digital – toes Central Region of the Body – head, neck, trunk Trunk – thorax, abdomen, pelvis Upper Limb - arm, forearm, wrist, & hand Arm – extends from shoulder – elbow Forearm – extends from elbow – wrist Lower Limb – thigh, leg, ankle, & foot Thigh – hip to knee Leg – knee to ankle 4 quadrants & 9 regions of abdomen: RightUpper Quadrant LeftUpper Quadrant RightLower Quadrant LeftLower Quadrant Occipital – base of skull Nuchal – back of neck Cranial – skull Scapular – shoulder blade Acromial – point of shoulder Vertebral – spinal column Lumbar – loin Olecranon – point of elbow Sacral – between hips Dorsum – back of hand Right Hypochondriac Region Epigastric Region Left Hypochondriac Region Right Lumbar Region Umbilical Region Left Lumbar Region Right Iliac Region Hypogastric Region Left Iliac Region Gluteal – buttock; Perineal – perineum; Sural – calf Popliteal – hollow behind knee; plantar – sole Calcaneal – heel Planes Sagittal – vertically through the body, separates left & right. Median – sagittal plane that passes through the midline, dividing equally left and right halves. Transverse/Horizontal – dividing into superior & inferior. Frontal/Coronal – divides anterior & posterior parts. Anatomy (dissect/cut) – structure; Physiology – function 2 basic approaches to the study of Anatomy: 1.
