Which bones primarily frame the forehead?

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

Answer: (B)

The frontal bone primarily frames the forehead. It is a singular bone that forms the anterior portion of the skull and is responsible for the forehead's structure and contour. This bone plays a crucial role in protecting the frontal lobe of the brain, providing a surface for muscle attachment, and contributing to the formation of the eye sockets (orbits). Its prominence is easily observable in the shape of the forehead, making its identification fundamental in understanding cranial anatomy. In contrast, the parietal bones are positioned on the sides and top of the skull, and while they contribute to the overall structure of the cranial cavity, they do not frame the forehead specifically. The temporal bones are found at the sides and base of the skull, encompassing the ear area, and have no direct involvement with the forehead. The sphenoid bone, located at the base of the skull and behind the eyes, serves as a crucial connector for other cranial bones but does not define or frame the forehead region.
