The vestibulocochlear nerve consists mostly of bipolar neurons and splits into two large divisions: the cochlear nerve and the vestibular nerve.. Cranial nerve 8, the vestibulocochlear nerve, goes to the middle portion of the brainstem called the pons (which then is largely composed of fibers going to the cerebellum).
Receives the special sense of taste from the epiglottis. A major function: controls muscles for voice and resonance and the soft palate. Symptoms of damage: dysphagia (swallowing problems), velopharyngeal insufficiency. This nerve is involved (together with nerve IX) in the pharyngeal reflex or gag reflex. XI Accessory
Nerves may be compressed because of increased intracranial pressure, a mass effect of an intracerebral haemorrhage, or tumour that presses against the nerves and interferes with the transmission of impulses along the nerve. [22] Loss of function of a cranial nerve may sometimes be the first symptom of an intracranial or skull base cancer. [23]
The following is a list of nerves in the human body: Location. Distribution of the areas of the sensory roots upon the surface of the body.
The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered. Auditory nerve fibers, fibers that travel through the auditory nerve (also known as the cochlear nerve or eighth cranial nerve) carry information from the inner ear, the cochlea, on the same side of the head, to the nerve root in the ventral cochlear ...
Olfactory nerve (cranial nerve 1) – smell; Optic nerve (cranial nerve 2) – sight; Oculomotor nerve (cranial nerve 3) – eye movement (except rotation) Trochlear nerve (cranial nerve 4) – eye rotation; Trigeminal nerve (cranial nerve 5) – sensation from the face and certain motor functions such as biting and chewing

Chief or pontine nucleus of the trigeminal nerve sensory nucleus (V) Motor nucleus for the trigeminal nerve (V) Abducens nucleus (VI) Facial nerve nucleus (VII) Vestibulocochlear nuclei (vestibular nuclei and cochlear nuclei) (VIII) Superior salivatory nucleus; Pontine tegmentum. Pontine micturition center ...
Type I neurons make up 90-95% of the neurons and innervate the inner hair cells. They have relatively large diameters, are bipolar, and are myelinated. Each type I axon innervates only a single inner hair cell, but each inner hair cell is innervated by up to 30 such nerve fibers, depending on species and location within the cochlea.
