Facial nerves. Historical anatomical artwork of a side view of a dissected human head showing the nerves (white) and muscles (red) of the face and neck. The facial nerves originate from a nerve called the seventh cranial nerve, also called the facial nerve. The left-hand facial nerve is seen here, emerging from below the ear. It branches out to ennervate the muscles of the face and scalp, and also the salivary glands and lacrimal glands of the eye (for tears). Sensory information comes from the tongue. Separate nerves in the neck run to the back of the scalp and to neck muscles. Artwork from The Nerves of the Human Body (Ed. Jones Quain, London, 1839).
