Frontal Bones

The frontal bone, also known as the os frontale, is a flat bone located on the upper front portion of the skull. It forms the anterior part of the cranium and makes up the forehead and root of the nose. The frontal bone plays an important role in facial structure, providing a protective shielding for the brain, as well as a platform for muscle attachments required for facial expressions. It also contains several important sinuses that help to reduce the weight of the skull. In addition, the frontal bone is essential for cognition and movement control. Apart from its protective and support function, it also helps to house the organs of hearing, taste, and smell. Overall, the frontal bone is essential for maintaining the integrity and shape of the skull, providing protection for the brain, and providing the support and attachment for facial muscles.
