Learn More Course The supraorbital nerve arises as a terminal branch of the frontal nerve (itself a branch of the ophthalmic division of the trigeminal nerve) within the roof of the bony orbit. It follows the levator palpebrae superioris muscle and then leaves the orbit via the supraorbital foramen, located at the superior aspect of the orbital rim. The supraorbital nerve emerges onto the forehead (accompanied by the supraorbital artery) and divides into sensory branches that supply the forehead and scalp.
