Skeletal system functions
supports, protects, allows bodily movement, produces blood, stores minerals
Depressions
flattened or indented portions of a bone; can be muscle attachment sites
Process
projection protruding from a bone; muscles, tendons, and ligaments can attach
Ligaments
connects bone to bone; little blood supply; slow to heal
Arthrokinematics
joint motion
Non-synovial joints
no joint cavity, connective tissue, or cartilage; little to no movement
Synovial joints
held together by joint capsule and ligaments; associated with movement
Major motion types
roll, side, and spin

hinge & ball-and-socket
Hinge
elbows, ankles; sagittal plane movement
Ball-and-socket
shoulders, hips; most mobile, all 3 planes of motion
