The pharyngeal nerve is a small branch of the maxillary nerve (CN V2),[1]: 496 arising at the posterior part of the pterygopalatine ganglion. It passes through the palatovaginal canal[1]: 370, 496 with the pharyngeal branch of the maxillary artery.[1]: 508
It is distributed to the mucous membrane of the nasopharynx[1]: 370, 496 (its posterior wall, posterior to the pharyngotympanic tube).[citation needed] It also issues some minute orbital branches which pass through the inferior orbital fissure to enter the orbit and innervate the periosteum of the floor of the orbit, and the mucosa of the sphenoid sinus and ethmoid sinus.[1]: 370
