Eighth cranial nerve

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.Through olivocochlear fibers, it also transmits motor and modulatory information from the superior olivary complex in the brainstem to the cochlea Eighth cranial nerve: The eighth cranial nerve is the vestibulocochlear nerve. The vestibulocochlear nerve is responsible for the sense of hearing and it is also pertinent to balance, to the body position sense.. Problems with the vestibulocochlear nerve may result in deafness, tinnitus (ringing or noise in the ears), dizziness, vertigo and vomiting. The 12 cranial nerves, the. eighth cranial nerve: (nerv) [L. nervus , sinew] NERVE STRUCTURE Parallel axons running together inside a thick connective tissue sheath (an epineurium). In the nerve, axons are wrapped into small bundles by thin connective tissue sheaths (endoneuria); each small bundle of axons is called a fascicle. The neuronal cell bodies of a nerve's axons. The eighth cranial nerve arises from the brain stem, which is connected with the spinal cord and is located at the base of the skull. It travels from the inner part of the ear towards the brain. In the inner ear are receptor cells that receive vibrations of sound and noise from the outside, which then stimulate the cochlear nerve to send these sounds to the brain for interpretation

Origin The vestibulocochlear nerve, or the eighth cranial nerve (CN VIII), is the sensory nerve which consists of two divisions. Each emerge from their respective roots: The vestibular root (gives rise to the vestibular nerve); The cochlear root (gives rise to the cochlear nerve); The roots arise from the vestibular and cochlear nuclei located in the brainstem The eighth cranial nerve carries two special sensory components, one in a cochlear division and one in a vestibular division. Both divisions innervate elaborate end-organs containing specialized mechanoreceptors (called hair cells because of their appearance), but accessory structures in the end-organs specialize the two divisions to respond to different types of mechanical stimuli

The 7th (facial) cranial nerve is evaluated by checking for hemifacial weakness. Asymmetry of facial movements is often more obvious during spontaneous conversation, especially when the patient smiles or, if obtunded, grimaces at a noxious stimulus; on the weakened side, the nasolabial fold is depressed and the palpebral fissure is widened
