Several structures of the facial nerve—described as nuclei, segments, and branches—produce the four components of facial nerve function. The facial nerve has: 1. six m...
The four components of the facial nerve include motor, sensory, taste, and parasympathetic function.
There are a few medical conditions that result in decreased function of the facial nerve.

The extent of recovery depends on the type and severity of the damage, how much of the nerve was involved, and the type of disease. If you have a tumor or some other mas...
Your facial nerves contain motor (movement), sensory and parasympathetic nerve fibers. Each of these types of nerve fibers has specific roles. Facial nerve parasympathetic functions. The parasympathetic nerve fibers of your facial nerves control the salivary glands in your mouth and the lacrimal glands in the corners of your eyes.
The facial nerve is the 7th cranial nerve and carries nerve fibers that control facial movement and expression. The facial nerve also carries nerves that are involved in taste to the anterior 2/3 of the tongue and producing tears (lacrimal gland).
