What is an Axial Skeleton?
The axial skeleton is the central and central core of the human body and is made up of the skull, vertebral column, and rib cage. The skull is made up of 22 bones that form the head and protect the brain. The vertebral column, also known as the spine, is made up of 33 bones (24 movable and 9 fused) that form the back and protect the spinal cord. The rib cage is made up of 12 pairs of ribs that connect to the vertebral column and form the chest cavity, which protects the heart and lungs.
The axial skeleton has several important functions, including:
- Support: The axial skeleton supports the body and provides attachment points for muscles.
- Protection: The axial skeleton protects the brain, spinal cord, heart and lungs.
- Movement: The axial skeleton allows for movement of the head, neck, and back.
- Blood production: The bone marrow in the axial skeleton produces red blood cells.
- Mineral storage: The axial skeleton stores minerals, such as calcium and phosphorus.
