The frontal bone is located at the front of the skull. It forms the forehead and the upper part of the eye sockets. The frontal bone plays a crucial role in protecting the brain and supporting facial structures. It also contributes to the overall appearance of the face. The frontal bone contains the frontal sinuses, air-filled cavities that help reduce the weight of the skull. Additionally, the frontal bone provides attachment points for various muscles involved in facial expressions and eye movements. Its position and shape contribute to the overall stability and functionality of the skull, as well as the aesthetics of the face.
