Diaphysis-Shaft of compact bone, long axis of the bone, Composed of compact bone tissue, Surrounds the medullary (marrow) cavity
Medullary cavity-Center of long bones, Contains yellow marrow (mostly fat) in adults, Contains red marrow (blood cell formation) in infants
Ends - Epiphysis-Compact bone around exterior, Interior contains spongy bone, Covered with articular (hyaline) cartilage
Articular cartilage-Covers the external surface of the epiphyses, Made of hyaline cartilage, Decreases friction at joint surfaces
Epiphyseal plate-Hyaline cartilage that grows during childhood to
lengthen the bone
Epiphysis Line-Where diaphysis and epiphysis meet in adult bones, Remnants of the growth plate
Membranes - Periosteum-External covering of the bone, Outer layer is fibrous connective tissue, Membrane contains nerves, blood vessels, and lymph
vessels
Membranes - Endosteum-Internal bone surface membrane in the medullary cavity, Covers the trabeculae of spongy bone and lines the canals of
the compact bone, Contains osteoclasts and osteoblasts
