metaphysis

Part of the bone between the epiphysis and the diaphysis; it contains the connecting cartilage enabling the bone to grow, and disappears at adulthood.

diaphysis

Elongated hollow central portion of the bone located between the methaphyses; it is made of compact tissue and encloses the medullary cavity.

distal epiphysis

Enlarged terminal part of the bone, farthest from the center of the body, made of spongy tissue and articulating with neighboring bones.

proximal epiphysis

Enlarged terminal part of the bone, nearest the center of the body, made of spongy tissue and articulating with neighboring bones.
