Long Bones: Parts Cont.

S Compact bone: section of the bone with no gaps which makes up the wall of the diaphysis

S Spongy bone: section of the bone with thin layer of bone with gaps which makes up the epiphysis

S Medullary cavity: hollow chamber in the middle of the diaphysis

S Endosteum: lines the medullary cavity and houses the bone-forming cells

S Marrow: connective tissue found in the gaps of bones.
