Axial skeleton comprises 80 bones distributed along the main axis of the body. The skull, vertebral column, sternum and ribs constitute axial skeleton. The skull is composed of two sets of bones – cranial and facial, that totals to 22 bones.

Cranial bones are 8 in number. They form the hard protective outer covering, cranium for the brain.

The facial region is made up of 14 skeletal elements which form the front part of the skull.

Our vertebral column is formed by 26 serially arranged units called vertebrae and is dorsally placed. The vertebral column is differentiated into cervical (7), thoracic (12), lumbar (5), sacral (1-fused) and coccygeal (1-fused) regions starting from the skull. The number of cervical vertebrae are seven in almost all mammals including human beings. 

There are 12 pairs of ribs. Each rib is a thin flat bone connected dorsally to the vertebral column and ventrally to the sternum.
