<P> The human skeleton is the internal framework of the body . It is composed of around 270 bones at birth -- this total decreases to around 206 bones by adulthood after some bones get fused together . The bone mass in the skeleton reaches maximum density around age 21 . The human skeleton can be divided into the axial skeleton and the appendicular skeleton . The axial skeleton is formed by the vertebral column , the rib cage , the skull and other associated bones . The appendicular skeleton , which is attached to the axial skeleton , is formed by the shoulder girdle , the pelvic girdle and the bones of the upper and lower limbs . </P>
