The parietal bone is defined as which of the following?

The parietal bone is defined as which of the following?

• A. Either of two skull bones between the frontal and occipital bones and forming the top and sides of the cranium
• B. The cheek bone
• C. The thigh bone
• D. The wrist bone

Answer: (A)

Parietal bones are the paired bones that form most of the roof and the upper sides of the skull, located between the frontal bone at the front and the occipital bone at the back. They meet the frontal bone along the coronal suture and the occipital bone along the lambdoid suture, with the two parietal bones joining along the sagittal suture. Their primary role is to protect the brain and provide attachment points for scalp muscles. The other options refer to different bones: the cheekbone is the zygomatic bone, the thigh bone is the femur, and the wrist bones are the carpal bones.
