General sensory information from the upper pharynx and posterior one-third of the tongue travel via the pharyngeal branches of CN IX. These peripheral processes have their cell body in either the superior or inferior glossopharyngeal ganglion.
Pharyngeal branches (rr. pharyngei) provide sensory innervation to the mucous membrane of the pharynx, tonsils, and soft palate. These branches create the anastomosis with the branches of the vagus nerve as well as with the branches of the sympathetic trunk to form the pharyngeal plexus.
