Chorda tympani carries taste from the anterior two-thirds and is a branch of which cranial nerve?

Taste from the front two-thirds of the tongue is carried by the chorda tympani, which is a branch of the facial nerve (cranial nerve VII). The chorda tympani exits the facial nerve in the middle ear, then joins the lingual nerve to reach the anterior tongue and convey the taste fibers. This contrasts with the posterior one-third of the tongue, where taste is carried by the glossopharyngeal nerve (cranial nerve IX). So the cranial nerve responsible for this taste pathway is cranial nerve VII.
