appendicular skeleton part of skeleton consisting of shoulder and pelvic girdles,arms and legs.
axial skeleton skeleton of head and trunk.
ball and socket joint diarthroses joint allows the greatest freedom of movement.
medullary canal Located in the center of diaphysis, filled with yellow bone marrow, mostly made of fat cells.
ossification the process when mineral matters starts to replace previously formed cartilage, creating bones.
bursa sacs small sac that cushion joints
circumduction circular movement at a joint.
osteocyte a mature bone cell.
periosteum a tough fibrous tissue which contatins blood vessels, lymph vessels, and nerves that covers the outside of the bone.
diaphysis shaft of long bone.
endosteum lining of the medullary cavity in the long bone.
epiphysis the end of the long bone.
extension act of increasing the angle between two bones.
flexion the act of bending a limb or decreasing the angle between two bones.
pronation the forearm turns the hand so the palm is downward or backward.
rotation movement allows a bone to move around one central axis.

arthritis inflammation of the joint.
suture immovable joint in cranial cavity.
bursitis inflammation of a bursa.

simple fracture closed fracture. when the bone is broken, but the broken ends do not pierce through the skin forming an external wound.
compound fracture(open) bone fragments pierce skin
greenstick fracture found in children
compound fracture(open) bone fragments pierce skin
comminuted fracture bones broken into many pieces
scoliosis side to side or lateral curvature of the sping
rheumatoid arthritis autoimmune disease of joints 3x more common in women
osteoarthritis degenerative joint disease
