Articular Surface

The surface covered in a smooth layer of cartilage over the epiphysis in which one bone forms a joint with another bone, providing a range of motion

Medullar cavity

Marrow-filled space within the diaphysis

Endosteum

Layer of bone that lines the medullar cavity which is similar in structure to ther periosteum but is thinner

Apophysis

Bony process of a bone

Cortex

Compact bone surrounding the medullary cavity
