What is the nature of the frontal bone?

• A. Single plate forming the sides of the head
• B. Pair of plates at the top and sides
• C. Single plate at the front of the cranium
• D. Group of small bones in the face

Answer: (C)

The frontal bone is a single bone located at the front of the cranium. It serves essential functions, including forming the forehead, the upper parts of the eye sockets (orbits), and contributing to the structure of the skull. As a flat bone, it provides protection for the brain and supports the structures of the face. Understanding the specific characteristics of cranial bones, such as the singular nature of the frontal bone, is important in anatomy, particularly when distinguishing between single and paired bones (like the parietal bones, which are paired and located on the sides of the head). The role of the frontal bone, being a singular structure, highlights its significance in cranial anatomy.
