Forehead

Forehead (a.k.a. the frontal region of the head) is the area located above the eyebrows and below the hairline. It extends laterally to the edges of the temples.

The layers of tissue in the forehead consist of the skin on the outside, followed by fat pads deeper within the forehead. Beneath the fat lies the muscular layer, which includes several superficial facial expression muscles such as procerus, occipitofrontalis, depressor supercilii and corrugator supercilii. The laterally positioned temporalis muscle occupies the side regions of the forehead.

The bony framework of the forehead primarily consists of the frontal bone. This bone features raised superciliary arches that form the superior orbital rim and define the lower boundary of the forehead. Between these arches lies a shallow bony depression called the glabella. Additionally, a supraorbital notch or foramen can often be found along each superior orbital rim (or superciliary arch).

In the lateral regions of the forehead, near the temples, the structure is supported by the temporal and the sphenoid bones.
