==Structure==
The bone of the forehead is the [[squamous part of the frontal bone]].<ref>{{cite book|title=Radiographic anatomy & positioning: an integrated approach|author=Diane H.

The sensory nerves of the forehead connect to the ophthalmic branch of the [[trigeminal nerve]] and to the [[cervical plexus]], and lie within the subcutaneous fat.  The motor nerves of the forehead connect to the [[facial nerve]].<ref name=Nouri1 /> The ophthalmic branch of the trigeminal nerve, the supraorbital nerve, divides at the orbital rim into two parts in the forehead.  One part, the superficial division, runs over the surface of the occipitofrontalis muscle.  This provides sensation for the skin of the forehead, and for the front edge of the scalp. The other part, the deep division, runs into the occipitofrontalis muscle and provides frontoparietal sensation.<ref name=KnizeDrisko />

Blood supply to the forehead is via the left and right superorbital, supertrochealar, and anterior branches of the [[superficial temporal artery]].<ref name=Nouri1 />
