ANATOMY
SKELETONFunctions of Skeleton:
- Mineral Storage, such as Calcium which is used for bone formation.
- Blood Cell Production, this takes place in Marrow where RBCs are formed.
- Protection, Mainly Flat bones.
- Support, muscles and organs are kept in place.
- Movement, different joints allow different types of movement.
-Short Bones allow for finer movements*.
-longer bones allow for grosser movements.
JOINTS
- Hinge, Extension and Flexion. Examples = knee and elbow.
- Ball and socket, Rotation and circumduction + abduction. Examples = shoulder and hip.
Synovial Joint:
- Synovial Membrane, secrets synovial fluid.
- Synovial Fluid, lubrication.
- Bursae, sacks of fluid which reduce friction.
- Ligaments, bands of fibre which attach bone to bone.
- Tendons, which attach muscle to bone.
- Joint capsule, support.
- Cartilage, tissue which prevents friction.
MUSCLESSternocleidomastoid, neck.
Deltoid, back of shoulder.
Trapezius, upper back.
- Antagonist=produce opposite movement to agonist.
- Agonist=prime mover.
- Isotonic=constant tension.
- Isometric=muscle changes length.
- Eccentric=lengthening of muscle.
- Concentric=shortening of muscles.
