spongy bone
strong, but gives the bone lightness, also for strength
marrow
creates blood cells
periosteum

anchor, does not move
insertion
muscle attatchment into bone that moves
levers
bones, simple machines, bones that actually move
antagonist muscle
muscles on either side of the bone, one contracts & one relaxes
elbow
pivot/fulcrum
sprain
injury to a ligament
strain
injury to a muscle
biceps
antagonist muscle in forearm
triceps
antagonist muscle in arm
ligament
tissue that holds bone together
avulsion
fracture where the muscle pulls away from the periosteum
incomplete fracture
fracture that does not go through the bone
complete fracture
fracture that goes through the bone
spiral fracture
fracture that spirals in the bone
compound fracture
bone comes through the skin
long bone
the femur bone and the humerous
short bone
