Todays Stations: • Independent Station: Correct Sub HW. Then work on Musculoskeletal Questions • Group Station: Make Flashcards for new terms. When you finish, Use Powerpoint on website for pictures to draw on flashcards • Direct Instruction: Teacher Check ins. Work on other 2 stations work Group Station Vocab List Directions: 1. Define each term on a flashcard 2. Once you finish each definition, draw picture for each flashcard • • • • • • • • • • • • • Smooth Muscle Skeletal muscle Cardiac Muscle Voluntary Muscle Involuntary Muscle Muscular System Skeletal System Musculoskeletal System Joints Tendons Antagonist Pair Extensor Flexor Do Now 1. Did you finish all of your HW due today? -How were you able to get it finished -Why weren’t you able to get it finished 2. How was your behavior with the sub. Rank yourself 1 – 10 and explain why you gave yourself that score 3. How was the class behavior with the sub. Rank the class 1-10 and explain why you gave the class that score 4. How do you feel about the new material about muscles? Why? 1. Lost, A little confused, Ok, I get most of it, I’m a master Wednesday, March 13th, 2013 Your Learning Goal: Students will be able to identify different types of joints and explain how muscles make your skeleton move Standard: 5c: Students know how bones and muscles work together to provide structural framework for movement.

Sub Review: Types of muscle • Skeletal Muscle: Voluntary muscles that pull on bones to help you move. These muscles allow you to move! – Striated (striped) muscles without branches. Skeletal muscles contract to pull on bones to move the bones. Forms bundles. • Smooth Muscle: Involuntary muscles that squeeze food through your digestive system. These muscles help you get nutrients! – Muscles in sheets that contract and squeeze food through the digestive system • Cardiac Muscle: Involuntary muscle in the heart that pumps blood through the body. This muscle pumps your blood! – Striated muscles that have branches. Cardiac muscles contract to pump blood out of the heart and into the arteries and relaxes to let blood into the heart. Sub Review: Types of muscle • Voluntary Muscle: Muscles that you control with your brain. You think and then you move. – Includes Skeletal Muscles • Involuntary Muscles: Muscles you can not control. These muscles work in your body without you thinking about it. They just work! – Includes Cardiac Muscle and Smooth Muscle Smooth Muscle images Smooth muscle under microscope Cardiac Muscle Cardiac Muscle under Microscop Skeletal Muscle Skeletal Muscle under the microscope What is our muscular system? • Muscular system: Muscles that provide movement for the body. – The muscular system is made up of skeletal muscles. – Muscles work when the brain sends the muscle a message. The message tells the muscle to contract (shorten). This pulls on the bone and causes movement. Levels of Organization Review 1. Atoms are the basic unit of matter. 2. Atoms work together to make molecules. 2.5. Organelles (not pictured) like mitochondria and the nucleus are made out of molecules working together. 3. Organelles work together to make a cell. Cells are the basic unit of life 4. The SAME cells work together to make a tissues – 5. 6. 7. Examples of tissues: Muscle tissue, nervous tissue, connective tissue, epithelial tissue Different tissues work together to make organs Organs work together to make an organ system Organ systems work together to make an organism Muscles are organs made out of different tissues Muscles are organs! • There are 600 different muscles in your body • Each different muscle is an organ. • Each muscles is made out of: – muscle tissue: The bundles of muscle cells that contract to pull on your bone – Nervous tissue: Tissue made out of cells that send messages from the brain to your muscle to tell it to contract – Connective tissue: The blood that delivers the sugar and oxygen so your muscles can work – Epithelial tissue: The cells that cover your muscles to protect them Muscular system is an organ system • The muscular system is all the skeletal muscles working together in your body to make you move • Each muscle is an organ • Organ systems are made out of organs working together • The muscular system is made out of muscles (organs) working together. Class Focus • We are going to focus on skeletal muscles. • We will talk about smooth muscle and cardiac muscle when cover the digestive and circulatory systems. What is the Skeletal System • Skeletal system- the framework of bones and other tissues that supports the body – Gives the body structure – Supports the weight of the body – Protects your internal organs (rib cage!) – Bone marrow inside the bone makes red blood cells • Our bodies are made up of 206 bones. • Babies have more than 206 bones because their bones have not fused (grown) together all the way What does the Skeletal System do? • • • • Gives the body structure Supports the weight of the body Protects your internal organs (rib cage!) Bone marrow inside the bone makes red blood cells What is the Musculoskeletal System • Musculoskeletal system: The organ system made up of muscles and bones working together • Organ parts: – – – – – Muscles Bones Joints Tendons Ligaments • Main jobs: Muscular system + Skeletal system – Provide Support for the body – Provides structural framework for movement What are joints? • Joints-the place where two or more bones meet. – Ex: the elbow joint or knee joint. Movement happens around joints. Pictures of different joints in the body What are tendons • Tendons are fibrous connective tissues that connect muscles to bone. How does skeletal muscles work • Muscles are connected to bone • When muscles contract, they shorten and pull on the tendon connecting it to the bone. • Muscles work in antagonist pairs What are antagonistic pairs • Antagonistic Pair: One muscle and contracts and pulls while the other muscle relaxes and extends. – Flexor: A muscle that pulls a limb into the body: BENDING – Extensor: A muscle that extends a limb away from the body: EXTENDING How do muscles work in Curls #getbig – The bicep contracts and pulls the forearm bone into the body and curls the arm. – The triceps relaxes and lets the forearm bend into the body. How do muscles work during throw ins! – The triceps contracts and pulls the forearm bone away from body and extends the arm. – The bicep relaxes and lets the forearm extend Tomorrows lesson: Do not continue What are GLIDING/SLIDING JOINT • Gliding joints are found in our wrists, ankles, and backbone. • Gliding joints do what they say: they glide past one another, and help us move those body parts. Carpals Pictures of sliding joints What are BALL AND SOCKET Ball and Socket Joints work look like a ball in a socket. They allow for 360 degree rotation (the most rotation of all the joints). The ball and socket joints in our body are our shoulders and hips. They work like joysticks on your video game controllers Examples of Ball and socket joints What are HINGE JOINTs • Hinge joints move up and down in one direction, like a door opening and closing. This type of joint can be found in our fingers, elbows, and knees. A hinge joint allows extension and flexing of an appendage Hinge Joints Example They work just like a door hinge. What are PIVOT JOINT • Pivot joints: one bone turns in the ring of another • Joint between 1st and 2nd neck vertebrae. And the joint connecting the radius and ulna of the for arm Questions • What is a joint? • Which joint gives you the most mobility? • Which type of joint do you have in your fingers? • Which type of joint only moves in 2 directions? • Which joint functions like:
