The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and salivary glands, and convey afferent information for taste from the anterior two-thirds of the tongue and for touch from the external ear.

This nerve arises from the inferior and lateral part of the tuber annulare, in the groove which separates it from the medulla oblongata, external to the corpora olivaria, and by the side of the auditory nerve. It issues from the cranium by the meatus auditorius internus; enters the aqueduct of Fallopius; receives a branch of the Vidian nerve; forms a gangliform swelling-Intumescentia gangliformis ;-sends off filaments to the internal muscles of the malleus and stapes; furnishes, according to many anatomists, that called Chorda Tympani; makes its exit at the foramen stylo-mastoideum, and divides into two branches-the temporo-facial, and cervica-facial. On the face it is termed Pes anserinus, Plexus nervorum anscrinus. See Portio Wrisbergii.
