The pharyngeal nerve (pterygopalatine nerve) is a small branch arising from the posterior part of the pterygopalatine ganglion.

It passes through the pharyngeal canal with the pharyngeal branch of the internal maxillary artery, and is distributed to the mucous membrane of the nasal part of the pharynx, behind the auditory tube.
