What is the structure of the axial skeleton?
The axial skeleton is the part of the skeleton that forms the central axis of the body. It consists of the skull, the vertebral column, the rib cage, and the sternum. The skull is made up of 22 bones, which protect the brain and other vital organs. The vertebral column is made up of 33 bones, which form the backbone and protect the spinal cord. The rib cage is made up of 12 pairs of ribs, which protect the heart and lungs. The sternum is a single bone that connects the ribs in the front of the chest.
The axial skeleton provides support and protection for the body's vital organs. It also allows for movement, such as bending, twisting, and turning.
