Facial nerve & facial expression (anatomy)

Ғылым және технология

The facial nerve is a bit of a beast, so let's just look at the part of this cranial nerve that innervates the muscles of facial expression. How can you use this anatomy to diagnose upper motor neurone (e.g. stroke) vs lower motor neurone (e.g. Bell's palsy) problems?

    Parotid Gland: 1- Sensory through the CN V2 (trigeminal - Mandibular). The nerve is Auriculotemporal nerve. 2- Secretomotor (Salivation) is through the postganglionic parasympathetic fibers of CN IX (glossopharyngeal - lesser petrosal nerve from tympanic nerve), which leaves the ganglion in accompany of (same together) as the CN V2 auriculotemporal nerve mentioned above. Is that in simple way terms correct? reminds us of Lacrimal gland - (CN V1 & CN VII)!!

    I realize this is an old video by now but if anyone knows, can these nerves be damaged by pressure from a nearby artery or by stimulants of the central nervous system? I've been having cramps followed by pain in several of these nerves following a treatment with a stimulant drug. The first six months I had lots of tension in the face and a loss of sense of "my brain" and impaired cognitive and emotional as well as sexual functioning.
