Musculoskeletal System: Parts of a Long Bone

wide ends of a long bone

shaft of a long bone

growth zone between epiphysis and diaphysis during development of a long bone

membrane lining the medullary cavity of a bone

cavity within the shaft of the long bones filled with bone marrow

soft connective tissue within the medullary cavities of bones

• Includes:
• - red bone marrow
• - yellow bone marrow

found in cavities of most bones in infants; functions in formation of red blood cells, some white blood cells, and platelets; in adults, red bone marrow is found most often in flat bones

gradually replaces red bone marrow in adult bones, functions as storage for fat tissue, and is inactive in formation of blood cells

a fibrous, vascular membrane that covers the bone

a gristle-like substance found on bones where they articulate
