2021-04-08 · When the vestibulocochlear nerve reaches the inner ear, it again splits into the vestibular and cochlear part which supply target tissues of the inner ear. Since they provide special sensory functions ( balance and hearing ) this nerve would be functionally categorized as special somatic afferent (SSA) instead of the general somatic afferent.

Damage to the vestibulocochlear nerve may cause hearing loss, vertigo, a false sense of motion, loss of equilibrium in dark places, nystagmus, motion sickness, and gaze-evoked tinnitus.

Since they provide special sensory functions ( balance and hearing ) this nerve would be functionally categorized as special somatic afferent (SSA) instead of the general somatic afferent. Vestibulocochlear nerve. The vestibulocochlear or eighth cranial nerve (CN VIII) has purely special sensory afferent function. The nerve has two components, the vestibular nerve, that detects head and body motion, and the cochlear nerve that detects sound. The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.

The 12 cranial nerves are the abducent, accessory, facial, glossopharyngeal, hypoglossal, oculomotor, olfactory, optic, trigeminal, trochlear, vagus, and vestibulocochlear nerve.

2 Aug 2020 Those who had good vestibular function on the side of VNS prior to surgery, experience a bigger change after the nerve is cut, and may have

2018-04-03 · Vestibulocochlear Nerve Location • The Vestibular Component arises from the vestibular nuclei complex, arising from the pons and the medulla. This • The Cochlear Component arises from the ventral and dorsal cochlear nuclei, which are present in the inferior • Hearing Function: The cochlear Vestibulocochlear Nerve Function (CN) VIII; Ear, Hearing, Balance The ear is the organ of hearing and balance. It comprises external (auricle and external acoustic meatus), middle and inner parts. Deformities of the auricle (figure 30), such as bat ears, are common and anomalies may be associated with syndromes such as Down’s.

This method allows assessment of cochlear and auditory nerve function The vestibulocochlear nerve action potential is typical of other nerve responses.

The vestibulocochlear nerve is the eighth paired cranial nerve. It is comprised of two parts – vestibular fibres and cochlear fibres. The vestibular nerve, located in each inner ear, is essential for regulating balance and sensing motion of the body. This paired nerve is part of the pathway that connects sensory fibers in the vestibular apparatus—three tiny structures called the semicircular canals, plus the saccule and utricle—to the brainstem (cerebellum). 1 The vestibulocochlear nerve (eighth cranial nerve, CN VIII, latin: nervus vestibulocochlearis) is a cranial nerve composed of two divisions, the vestibular and cochlear nerve, both purely sensory in function. The vestibulocochlear nerve carries special somatic afferent fibers from structures of the inner ear. Functioning of Vestibulocochlear Nerve The vestibulocochlear nerve is also called the acoustic or the auditory nerve.
