Infraorbital Nerve

The maxillary nerve divides into the large Infraorbital, zygomatic, and pterygopalatine nerves. The maxillary nerve carries sensation from the skin of the face and the mucosa and teeth in the maxillary region. The ganglion rami (pterygopalatine) carry sensory fibers from the mucosa of the nasal, palatal and pharyngeal regions and convey postganglionic fibers from the pterygopalatine ganglion and sympathetic fibers (via the ganglion grom the deep pertrosal nerve) from the lacrimal gland back to the maxillary nerve (and further to the zygomatic nerves). Superior labial, inferior palpebral, and lateral nasal cutaneous branches converge to form the infraorbital nerve which passes through the infraorbital foramen of the maxilla and traverses the infraorbital canal with the infraorbital artery. It is joined by anterior branches of the superior alveolar nerve and in the pterygopalatine fossa becomes the maxillary nerve (V2).
