Through these messages, the facial nerves control the muscles of your face, forehead, and neck.Facial nerves control the expressions like raising your eyebrows, squeezing your eyes shut, or smiling. Each facial nerve starts in the brain, goes through the skull in a narrow tube of bone, and exits the skull behind the ear. From there, it splits into smaller branches of nerves that attach to the muscles of the face, neck, and ear. Other small nerve branches run to the glands that make saliva, the glands that make tears, and the front of the tongue..
