The Facial Nerve (Cranial Nerve VII)

The seventh cranial nerve comes from the pons of the brainstem[1]. The facial nerve is responsible for facial expression and conveyance of taste sensation for the front two thirds of the tongue[1]. This is both a motor and sensory nerve[2]. Facial nerve testing can be done by showing your teeth, puffing your cheeks, wrinkling your brow, frowning, and closing your eyes tightly[2]. Essentially, this nerve controls all the funny faces you can make!
