The chorda tympani is an afferent nerve, which arises as a branch of the facial nerve (CN VII). It runs through the tympanic cavity of the ear to join the mandibular nerve. It carries taste sensation from the anterior 2/3rd of the tongue. The chorda tympani also contains parasympathetic preganglionic fibers that go to the salivary glands.
