The axial skeleton includes bones of the head, neck, and trunk, not the limbs.

Examples of bones that are part of the axial skeleton include:

  • Skull bones (such as the frontal bone, parietal bone, and occipital bone).
  • Vertebrae of the vertebral column (cervical, thoracic, lumbar, sacrum, coccyx).
  • Ribs.
  • Sternum.
  • Hyoid bone.

So, if you are choosing one bone that is part of the axial skeleton, a correct answer would be, for example, the frontal bone (or any vertebra, rib, sternum, or hyoid bone).

Quick Scoop: Extra context

The human skeleton is divided into:

  • Axial skeleton: 80 bones (skull, vertebral column, ribs, sternum, hyoid).
  • Appendicular skeleton: 126 bones (shoulder girdles, upper limbs, pelvic girdle, lower limbs).

A simple way to remember:

  • Axial = the axis of your body (central line: head, neck, trunk).
  • Appendicular = what “hangs off” that axis (arms and legs and their girdles).
