Long Bones: Parts Epiphysis: “knobby” ends of the long bones Articular cartilage: Outside portion of the epiphysis which provides smooth glide for joints Diaphysis: The narrow, length section of a long bone Periosteum: outermost covering of fibrous tissue on the bone

Long Bones: Parts Cont. Compact bone: section of the bone with no gaps which makes up the wall of the diaphysis Spongy bone: section of the bone with thin layer of bone with gaps which makes up the epiphysis Medullary cavity: hollow chamber in the middle of the diaphysis Endosteum: lines the medullary cavity and houses the bone-forming cells Marrow: connective tissue found in the gaps of bones.
