Which nerve provides taste to the anterior two-thirds of the tongue?

Explanation:
Taste from the anterior two-thirds of the tongue is carried by the chorda tympani, a branch of the facial nerve. It contains special visceral afferent (taste) fibers that join the lingual nerve (a branch of V3) to reach the tongue. This is why taste travels with the chorda tympani into the tongue rather than with the lingual nerve itself, which provides only general sensation (touch, pain, temperature). The posterior one-third is served by the glossopharyngeal nerve, and taste to the epiglottis is via the vagus. So the chorda tympani is the nerve responsible for taste in that anterior region.
