Forehead

Forehead is the superior region of the upper face. It commences from the hair line above and extends below to the superior rim of the orbital cavity.

The tissue layers of the forehead include the skin on the outside. Deeper to the skin lie fat pads of the forehead. Further deep lies the muscular layer which comprises of various superficial muscles of facial expression, including the procerus, occipitofrontalis, depressor supercilii and corrugator supercilii muscles, while the temporalis muscle occupies the lateral forehead space.

The bony structure of forehead mainly comprises of the frontal bone, which is characterized by raised superciliary arches that form the superior orbital rim and mark the lower extent of the forehead. The bony depression in between the two superciliary arches is called glabella. A supraorbital notch or foramen can also be found in each superior rim of the orbit (or superciliary arch).

The bones in the lateral forehead–in the temporal region–mainly include the temporal and the sphenoid bones.
