Chp.8 skeletal and muscular systems - created from Mind Map

parts of human skeleton diagram do not need joints and stermum missing collar bone/shoulder blade

functions of skeleton support provides rigid base against which muscles pull on protection

types of joints fixed/fused joint freely moving joints(synovial joints) no movement allowed bone in skull ball and socket hinge cartilage covers ends of bones movement in all directions shoulder/hip movement in one direction only elbow/knee produce lubricating liquid(synovial fluid)

cartilage,tendons,ligaments cartilage tendons ligaments covers and protects ends of bones connect muscles to bone connect bones to bones

muscles made of protien can only contract(get shorter) work in antagnostic pairs(opposite pairs)

antagonistic pair of muscles biceps and triceps are antagonistic triceps contract to lower forearm biceps contract to raice forearm
