Which bone is known to form the forehead?

The frontal bone is the key structure that forms the forehead. It plays a crucial role in the anatomy of the skull, providing the anterior (front) portion and contributing to the formation of the eye sockets and the nasal cavity. This bone is easily identifiable as the section of the skull that extends from the forehead down to the eyebrows and up to the hairline.

Understanding the significance of the frontal bone helps contextualize its protective function for the frontal lobes of the brain, as well as its contribution to facial aesthetics and the skull's overall shape. In contrast, the occipital bone is located at the back of the skull, the temporal bone is situated on the side of the skull near the ears, and the parietal bone forms the upper sides and roof of the cranium. Each of these bones serves distinct purposes and locations within the skull’s anatomy. The frontal bone's role is unique and necessary for defining the forehead area.
