Its name ("trigeminal" = tri-, or three, and - geminus, or twin: so "three-born, triplet") derives from each of the two nerves (one on each side of the pons) having three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3).
What is the primary motor nerve of the face?
trigeminalNerve, trigeminal: This nerve functions both as the chief nerve of sensation for the face and as the motor nerve controlling the muscles of mastication (chewing).
What causes facial expressions?
Facial expressions are vital to social communication between humans. They are caused by the movement of muscles that connect to the skin and fascia in the face. These muscles move the skin, creating lines and folds and causing the movement of facial features, such as the mouth and eyebrows.
What are facial expressions controlled by?
These two types of facial expressions are controlled from two distinctly different areas of the brain: the emotional center (limbic system) and the volitional center (motor cortex).
Where does the facial nerve emerge from?
ponsThe motor root of the facial nerve originates in the facial (motor) nerve nucleus in the pons of the brainstem, which receives input from a number of other structures and brain regions, including the primary motor cortex and the ophthalmic division of the trigeminal nerve.
What nerve innervates the skin of the face?
the trigeminal nerveThe primary source of cutaneous innervation of the face is the trigeminal nerve (cranial nerve CN V) with its three divisions, i.e. ophthalmic nerve (V1), maxillary nerve (V2), and mandibu- lar nerve (V3) (Shankland 2000).

Cranial Nerve 8 travels a similar path as Cranial Nerve 7, the Facial Nerve, extending out of the brainstem right next to each other. The purpose of CN8 is hearing and balance.
What is a NF2 tumor?
The hallmark issue of Neurofibromatosis Type 2 (NF2) is the bilateral growth of schwannoma bilaterally on cranial nerve 8 (CN8) , the nerve in the brain vestibulocochlear nerve. CN8 has two branches of different function the cochlear (auditory) nerve branch for hearing and the vestibular nerve branch for balance. These tumors are either called acoustic neuroma (AN) or vestibular schwannoma (VS).

What causes facial nerves to twitch?
Facial nerve disorders, also known as facial nerve dysfunction or facial paralysis, can be caused by infections, disorders and trauma. Your facial muscles lose movement due to nerve damage resulting in weakness, twitching in the face to sometimes full paralysis. This can affect one or both sides of your face. The most common form of facial nerve disorders is Bell’s Palsy. According to the National Institute of Neurological Disorders and Stroke, approximately 40,000 Americans each year are affected by this.
