Skeleton


The skeleton is a mobile framework made up of 206 bones, approximately half of which are in the hands and feet. Although individual bones are rigid, the skeleton as a whole is remarkably flexible and allows the human body a huge range of movement. The skeleton serves as an anchorage for the skeletal muscles, and as a protective cage for the body’s internal organs. Female bones are usually smaller and lighter than male bones, and the female pelvis is shallower and has a wider cavity.
