Maxillary Nerve

Last updated: Jan 14th, 2025

The maxillary nerve is one of the three large branches of the trigeminal sensory nerve. This includes the ophthalmic, maxillary, and mandibular divisions. The fibers of the maxillary division (including the infraorbital nerve, which branches into a superior alveolar nerve) carry sensory impulses from the upper teeth, upper gum, and upper lip, and from the mucous lining of the palate and the skin of the face.
