Skeletal System

the rounded end of a long bone(red marrow found in spongy + make red blood cell)

the central part of the bone(yellow marrow found)

found in the diaphysis, 100% bone, no cavities

in the epiphysis a dense bone, contains red marrow

provide nutrient blood for bone cells and source of osteoprogenitor cells; not cover articular cartilage

the thin layer of cells lining the medullary cavity of a bone

found in the hollow interior of the middle portion of long bones; blood loss body convert yellow marrow to red marrow increase blood cell production

found mainly in the flat bones,hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") bone at the epiphysis ends of the long bones such as the femur and humerus
