What bones make up the axial skeleton?

• A. Skull, spine, and chest
• B. Limbs
• C. Pelvis
• D. Rib cage only

Answer: (A)

The axial skeleton forms the central axis of the body, protecting the brain, spinal cord, and thoracic organs, and providing support for the head and trunk. It includes the skull, vertebral column (spine), and thoracic cage (ribs and sternum). Saying skull, spine, and chest captures these core parts, so it’s the best description. Limbs and the pelvis belong to the appendicular skeleton, and a rib cage alone omits the skull and spine.
