Supraorbital nerve

The supraorbital nerve is a terminal branch of the frontal nerve.

It passes through the supraorbital foramen, and gives off, in this situation, palpebral filaments to the upper eyelid.

It then ascends upon the forehead, and ends in two branches, a medial and a lateral, which supply the integument of the scalp, reaching nearly as far back as the lambdoidal suture; they are at first situated beneath the Frontalis:
 * the medial branch perforates the muscle.
 * the lateral branch perforates the galea aponeurotica.

Both branches supply small twigs to the pericranium.
