Which bones are included in the axial skeleton?

• A. Ossicles, skull, scapula, vertebrae
• B. Cranium, facial, sternum, vertebrae
• C. Vertebrae, pelvic, skull, ribs
• D. Rib, sternum, hyoid, clavicle

Answer: (B)

The axial skeleton consists of the bones that form the central axis of the body, which includes the skull, vertebral column, and rib cage. The correct choice includes the cranium and facial bones of the skull, along with the sternum and vertebrae. The cranium protects the brain, while the facial bones provide structure to the face and form the cavities for the eyes, nose, and mouth. The vertebrae are the individual bones that make up the spine, providing support and protecting the spinal cord. The sternum aids in the protection of vital organs in the thorax and serves as an anchor point for the ribs. Other options contain bones that are not part of the axial skeleton. For instance, the scapula and clavicle are part of the appendicular skeleton, which supports the limbs. The pelvic bones are also part of the appendicular skeleton. Therefore, the inclusion of the correct bones in the answer reflects a solid understanding of the axial skeleton's structure and function.
