The lingual (tongue) branch of the sensory component of the Glossopharyngeal Nerve (CN IX) conveys information about taste and other sensations from receptor cells located in the throat and on the posterior third of the tongue.

The sensory portion of CN IX arises from the taste buds on the posterior third of the tongue and via the carotid sinus passes through the jugular foramen ending in the medulla (Parent, 1996). Proprioceptive receptors from the stylopharyngeus muscle are also conveyed by this cranial nerve.
