Wrinkle In Time Quiz - Cranial Nerve Vii - The Facial Nerve and How to Test Its Function Good afternoon. Yesterday, I learned about Wrinkle In Time Quiz - Cranial Nerve Vii - The Facial Nerve and How to Test Its Function. Which could be very helpful in my opinion therefore you.

The seventh cranial nerve is predominantly a motor nerve supplying the muscles of facial expression.

It just isn't the final outcome that the actual about Wrinkle In Time Quiz. You check out this article for information on that want to know is Wrinkle In Time Quiz. Wrinkle In Time Quiz The taste fibers are carried by the lingual nerve, which is a subject of the mandibular nerve and these fibers join the chorda tympani. The motor nucleus of the seventh nerve lies previous and lateral to the abducens nucleus in the lower pons. The intrapontine fibers hook nearby the sixth nerve nucleus to emerge at the cerebellopontine angle, lateral to the corticospinal tract. Along with the auditory canal through the internal auditory neatus. Anterioly it bends sharply forward and downward, and at this angle lies the geniculate ganglion. Distally, the nerve exits through the stylomastoid foramen. Immediately after its exit from the skull, the nerve passes through the parotid gland, and gives rise to five branches to provide the orbicularis oculi, orbicularis oris, frnatalis, zygomatic muscles, buccinator, platysma and other muscles of facial expression.
