Which portion forms the axial skeleton and protects the spinal cord?

Explanation:
The axial skeleton includes the skull, vertebral column, and rib cage, and its job includes protecting the central nervous system. The vertebral column specifically forms the protective column around the spinal cord: the vertebral foramen of each vertebra creates a canal, and stacking them gives a protective tunnel that shields the spinal cord while allowing nerve passage between vertebrae. The other options don’t encase the spinal cord in this way—ribs protect the heart and lungs, the pelvis supports weight and provides attachment for the legs, and the mandible is a facial bone. So the vertebral column is the structure that forms the axial skeleton and protects the spinal cord.
