The Axial skeleton consists of the bones along the axis of the body: The Cranium; the Sternum; the Rib Cage; the Spine (Vertebrae) and the Coccyx. In the human skeleton it consists 80 bones. Some examples of what the main roles of the Axial skeleton are: The Cranium protects the brain from any external damage. The Ribcage and Sternum protect the heart and lungs from any external damage. The Vertebrae provides strength and support for the human body and allows the brain to send nerve impulses. The Axial skeleton has two main functions. One is to provide protection for vital organs such as the brain, heart and lungs. Another is that it gives a surface for muscles to attach to. The main role of the Appendicular skeleton is that it holds and supports the limbs of the human body and allows movement. The Appendicular skeleton consists
