OverviewThe skeleton is made up of 206 bones in the adult and contributes to the form and shape of the body. The skeleton has several important functions for the body. The bones of the skeleton provide support for the soft tissues. For example, the rib cage supports the thoracic wall. Most muscles of the body are attached to bones which act as levers to allow movement of body parts. The bones of the skeleton also serve as a reservoir for minerals, such as calcium and phosphate. Finally, most of the blood cell formation takes places within the marrow of certain bones.
