Which bone forms the side and top portion of the skull?

• A. Parietal bones
• B. Temporal bones
• C. Frontal bone
• D. Occipital bone

Answer: (A)

The parietal bones form the sides and roof of the skull. They are paired bones that meet along the sagittal suture at the top of the head, creating the main dome that covers the brain. They also articulate with the frontal bone at the coronal suture, with the occipital bone at the lambdoid suture, and with the temporal bones along the squamous sutures on the sides. This positioning makes them the primary bones that define the skull’s side and top. The frontal bone forms the forehead and anterior roof, the temporal bones are located at the lower sides near the ears, and the occipital bone forms the back and base of the skull.
