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).
V 1 (ophthalmic nerve) is located in the superior orbital fissure V 2 (maxillary nerve) is located in the foramen rotundum. V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the ...

The olivocochlear system is a component of the auditory system involved with the descending control of the cochlea.Its nerve fibres, the olivocochlear bundle (OCB), form part of the vestibulocochlear nerve (VIIIth cranial nerve, also known as the auditory-vestibular nerve), and project from the superior olivary complex in the brainstem to the cochlea.
The receptor cells located in the semicircular ducts are innervated by the eighth cranial nerve, the vestibulocochlear nerve (specifically the vestibular portion). The crista ampullaris itself is a cone-shaped structure, covered in receptor cells called "hair cells".
The internal auditory meatus provides a passage through which the vestibulocochlear nerve (CN VIII), the facial nerve (CN VII), and the labyrinthine artery (an internal auditory branch of the anterior inferior cerebellar artery in 85% of people) can pass from inside the skull to structures of the inner ear and face.
The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information from 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 .
