Quizplus · Accepted Answer

The glossopharyngeal nerve (cranial nerve IX) is responsible for taste sensations from the posterior third of the tongue, but not the entire tongue. The anterior two-thirds are innervated by the chorda tympani branch of the facial nerve (cranial nerve VII), so damage to the glossopharyngeal nerve would not result in a complete loss of taste.
