Facial nerve
The facial nerve is the seventh cranial nerve. It is a mixed nerve that has fibers both going out and coming in (both efferent and afferent fibers). It supplies the muscles of facial expression. Paralysis of the facial nerve causes a characteristic picture with drooping of one side of the face, inability to wrinkle the forehead, inability to whistle, inability to close the eye and deviation of the mouth toward the other side of the face. Paralysis of the facial nerve is called Bell's palsy.
