1 Bones
2 Skeleton
2.1 Contains more than 200 bones
2.2 Bones
2.2.1 Is a living tissue with a blood supply
2.2.2 Calcium makes them strong
2.2.3 Is constantly dissolved and made
2.2.4 Bones are made from 3 main materials... Protein Organic material called Collagen Minerals Calcium Phosphorus Marrow Red Produces Red Blood Cells Yellow Stores Fat All give structure to the bones
2.3 Function of skeleton and bones
2.3.1 Protection Bone is rigid and tough so it can protect soft, delicate organs Hard and flexible E.g. Skull protects brain
2.3.2 Support Creates a frame for other body parts to use (hang off) E.g. Without a back bone, we would not be able to stay straight and upright E.g. Femur supports the leg
2.3.3 Movement Bones are rigid and solid Muscles can be attached to them via tendons Joints
2.3.4 Contains marrow Helps make blood Keeps bone alive
3 Joints
3.1 3 Types
3.1.1 Hinge Knee Move in only one direction Elbow Moves in only one direction
3.1.2 Fixed Skull- cannot move
3.1.3 Ball and Socket Hip Move in pretty much any direction
3.2 A joint is where two bones meet
3.3 Help you move easier
3.4 Held together by Ligaments
3.5 Cartilage prevents the bones from rubbing together
3.6 Synovial Fluid keeps the cartilage slippery
4 Muscles
4.1 Ligaments hold bone to bone
4.2 Tendons hold bones to muscles
4.3 Antagonistic Muscles
4.3.1 They are a pair of muscles that work against each other One muscle contracts (shortens) while the other relaxes (lengthens) Or Vice Versa
4.3.2 Attached to bone through tendons so they can pull on bone
4.3.3 One muscle pulls the bone in one direction and the other muscle pulls it in the other direction, causing the joint to move
4.4 Muscles only pull and not push so that is why they can come in pairs...
