Multiple Choice

Which nerve provides taste sensation from the epiglottis?

Taste from the epiglottis travels with the vagus nerve. The sensory fibers carrying this taste information run through the internal branch of the superior laryngeal nerve, which is a branch of X, and then to the brainstem. This fits because the vagus supplies sensory (including taste) information from the larynx and epiglottis, whereas glossopharyngeal handles taste from the posterior tongue and oropharynx, facial handles taste from the anterior two-thirds of the tongue, and the hypoglossal nerve is motor to the tongue, not involved in taste.
