The course of the facial nerve from its origin in the human brain-stem to the termination of its end fibers in the muscles of facial expression is reviewed in detail. The relation of the facial nerve to important adjacent structures is emphasized so that the aural surgeon is better prepared to explo The facial nerve (seventh cranial nerve, CN VII, latin: nervus facialis) is a mixed cranial nerve consisting of motor, sensory, and visceromotor fibers. The main functions of the facial nerve include controlling the muscles of facial expression, and providing taste sensations from the anterior part of the tongue. AN Model Viewer The facial nerve has a complex anatomy. It is one of the longest cranial nerves, extending from the brainstem to the terminal (end) branches, which are located throughout the face. Several structures of the facial nerve—described as nuclei, segments, and branches—produce the four components of facial nerve function The facial nerve (CN VII) is the seventh paired cranial nerve. In this article, we shall look at the anatomy of the facial nerve - its anatomical course, functions and clinical correlations.
