The arises from the
Orbit by the supraorbital foramen and supplies the upper
Eyelid and forehead integuments. It forms the
Frontal Nerve with the
Supratrochlear Nerve . The frontal nerve joins the
Nasociliary and
Lacrimal Nerve s to form the
Ophthalmic Division (V1) of the
Trigeminal Nerve (
Cranial Nerve V).
The supraorbital nerve 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 perforating the muscle, the lateral branch the
Galea Aponeurotica . Both branches supply small twigs to the
Pericranium .
