The vestibulocochlear nerve has a cochlear part (COCHLEAR NERVE) which is concerned with hearing and a vestibular part (VESTIBULAR NERVE) which mediates the sense of balance and head position. All of the pertinent anatomical topics are conveniently organized to instruct on anatomy, but also on how to examine the functioning of this anatomy in the patient. Vestibulocochlear nerve VIII The vestibulocochlear nerve [VIII] carries SA fibers for hearing and balance, and consists of two divisions: 1. a vestibular component for balance. Hypoglossal Nerve. Yesterday at 9:49 pm. There are two special sensory cochlear nuclei and four special sensory vestibular nuclei located within the lower pons and upper medulla.

This includes the cranial nerves, which transmit information between the brain and parts of the head and neck. The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord.These nerves form the communication network between the CNS and the body parts. It travels from the inner ear to the brainstem and out through a bone located on the side of the skull called the temporal bone. Location in English Hierarchy of Brain Structures.

Schwannomas most commonly arise in the head and neck region, most commonly developing from the vestibulocochlear nerve. (2021). Patients typically present with ipsilateral oculomotor nerve palsy, crossed hemi-ataxia, incoordination, and chorea (1,5).

Vestibulocochlear nerve Your vestibulocochlear nerve has sensory functions involving hearing and balance. Figure VIII2 Bony and membranous labyrinths of the vestibulocochlear nerve, cranial nerve VIII (removed from the surrounding petrous temporal bone). The vestibulocochlear nerve is the eight cranial nerve (CN VIII) and it is a purely sensory nerve. The information and facts mentioned in the write-up are a number of the most effective available. In humans the vestibular nerve transmits sensory information transmitted by vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three semicircular canals via the vestibular ganglion of Scarpa. INTRODUCTION Stato-acoustic or Auditory nerve 8th cranial nerve 2 components: a) cochlear (hearing) b) vestibular (equilibrium) OBJECTIVES 1) Anatomy and functions. Number: VIII Name: Vestibulocochlear (also known as the auditory-vestibular or acoustic nerve) Sensory, motor, or both: Mostly sensory Origin/Target: Lateral to CN VII (cerebellopontine angle) Nuclei: Vestibular nuclei, Cochlear nuclei Function: Senses sound, rotation, and gravity (essential for balance and movement).More specifically, the vestibular branch carries The Peripheral Nervous System. The vestibulocochlear nerve, also called the auditory vestibular nerve, is responsible for hearing and balance. This is situated in the long spiral canal of the cochlea. The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles.It is classified as the eleventh of twelve pairs of cranial nerves because part of it was formerly believed to originate in the brain.
