Definition : The 7th cranial nerve. The facial nerve has two parts, the larger motor root which
may be called the facial nerve proper, and the smaller intermediate or sensory root.
Together they provide efferent innervation to the muscles of facial expression and
to the lacrimal and salivary glands, and convey afferent information for taste from
the anterior two-thirds of the tongue and for touch from the external ear. [MeSH];
