Taste sensation from the anterior two-thirds of the tongue is carried by which cranial nerve?

Explanation:
The question tests which nerve carries taste from the front two-thirds of the tongue. Taste from the anterior two-thirds travels with the chorda tympani, a branch of the facial nerve, to reach the tongue and then the brain via the nucleus of the solitary tract. The glossopharyngeal nerve handles taste from the posterior third, and the vagus handles taste in other areas like the epiglottis. The trigeminal nerve provides general sensation (not taste) from the anterior tongue. So the anterior two-thirds’ taste is carried by the facial nerve.
