PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - The skeleton comprises cartilage and bone and is a support for the insertion of muscles and tendons enabling movement, a shield for soft tissue organs, a site for storage of bone marrow, and a reserve pool of calcium, phosphate, and other ions. There are flat (eg, cranium, scapula, pelvis) and long (eg, humerus, femur, phalanges) bones. The outer surface of bone is enclosed in periosteum (a fibrous network of osteoblasts that synthesizes peripheral compact bone); endosteum lines its inner surface. The central portion of long bones is a hollow shaft of dense cortical bone termed the diaphysis; at both ends of many long bones are the metaphysis (composed of cortical and cancellous or trabecular bone), cartilaginous growth plate, and epiphysis.
