The axial skeleton includes the skull, spinal column, sternum, and ribs. This part of the skeleton serves as the central framework of the body, providing support and protection for the brain, spinal cord, and thoracic organs. The skull protects the brain and forms the structure of the face, while the spinal column encases and protects the spinal cord. The sternum and ribs are crucial for protecting vital organs in the chest and also play a significant role in the respiratory system by assisting in the mechanics of breathing.

The appendicular skeleton, in contrast, comprises the bones of the limbs and the supportive girdles that connect them to the axial skeleton. The pelvic girdle includes bones that support the lower limbs and the shoulder girdle supports the upper limbs. As such, these options do not include the skull, spinal column, sternum, and ribs, thereby distinguishing the axial skeleton as the correct answer in this context.
