bone parts practice

anatomy and physiology practice for bones' parts; high school level
ends of the bone; increase load bearing surface
shaft of the bone; hollow so the bone is not too heavy
epiphyseal line
where the epiphysis and diaphysis meet; where the bones grow in length
spongy bone
at the head of the epiphysis and beginning of diaphysis
medullary cavity
hollowed out section of shaft; stores blood cells
covering the layer of the bone; protective layer where there is no articular cartilage
compact spongy bone
surrounds bone; gives strength to the hollow part of the bone
bone marrow
what's in the medullary canal; blood cells are made here
articular cartilage
on ends of bone; stops the ends of bones from rubbing together and absorbs the shock
in front of and behind the patella; produces synovial fluid; keep ligament off bone to prevent wear
synovial fluid
underneath synovial capsule; to lubricate
synovial capsule
behind the end of the femur; ligaments to hold joint together
strip underneath patella; further strength articulation
bumps on bone that increase surface area for muscle attachment
