CRANIAL NERVE VIII: VESTIBULOCOCHLEAR NERVE

on 1.12.06 with 0 comments



VESTIBULAR NERVE:
  • Innervates the semicircular canals, utricle, and saccule, and is responsible for dynamic and static balance.

COCHLEAR NERVE:

  • Innervates the cochlea and is responsible for hearing.

INTERNAL ACOUSTIC MEATUS: Cranial Nerve VIII exits out the internal acoustic meatus, along with the Facial Nerve.

ACOUSTIC NEUROMAS: A neuroma from a Schwann Cell in the Vestibulocochlear may impinge upon the Vestibular and Cochlear nerves in the Internal Acoustic Meatus. If it is large enough, it may impinge on the Facial Nerve, too.
