The axial skeleton consists of the vertebral column, which includes the bones that form the spine, as well as the thorax, which contains the ribs and sternum. The vertebral column provides structure and protection to the spinal cord and supports the weight of the head and upper body. The thorax protects the lungs and heart by the rib cage and sternum.
