The vestibular nerve is one of the two branches of the Vestibulocochlear nerve (the cochlear nerve being the other). Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. This is a list of the subjects in Gray's Anatomy: IX Neurology The vestibulocochlear nerve (also known as the auditory or acoustic nerve) is the eighth of twelve Cranial nerves, and is responsible for transmitting sound Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The vestibulocochlear nerve (also known as the auditory or acoustic nerve) is the eighth of twelve Cranial nerves, and is responsible for transmitting sound The cochlear nerve (also auditory nerve or VIIIth nerve) is part of the Vestibulocochlear nerve, (or 8th Cranial nerve) that is found in higher It goes to the semicircular canals via the vestibular ganglion. The semicircular canals are three half-circular interconnected tubes located inside each Ear that are the equivalent of three Gyroscopes located in three orthogonal The vestibular ganglion (also called Scarpa's ganglion) is the Ganglion of the Vestibular nerve. It receives positional information.
Axons of the vestibular nerve synapse in the vestibular nucleus on the lateral floor and wall of the fourth ventricle in the pons and medulla. The vestibular nuclei are the Cranial nuclei for the Vestibular nerve. The fourth ventricle is one of the four connected fluid-filled cavities within the human Brain. The pons (sometimes pons Varolii after Costanzo Varolio) is a structure located on the Brain stem.
It arises from bipolar cells in the vestibular ganglion, ganglion of Scarpa, which is situated in the upper part of the outer end of the internal auditory meatus. A bipolar cell is a type of Neuron which has two extensions Bipolar cells are specialized sensory neurons for the transmission of special senses The vestibular ganglion (also called Scarpa's ganglion) is the Ganglion of the Vestibular nerve. The internal acoustic meatus (also internal auditory meatus) is a canal in the Temporal bone of the skull that carries nerves from inside the cranium towards the middle

Branches
The peripheral fibers divide into three branches (some sources list two)[1]:
- the superior branch passes through the foramina in the area vestibularis superior and ends in the utricle and in the ampullae of the superior and lateral semicircular ducts;
- the fibers of the inferior branch traverse the foramina in the area vestibularis inferior and end in the saccule;
- the posterior branch runs through the foramen singulare and supplies the ampulla of the posterior semicircular duct. The lateral or horizontal canal (external semicircular canal is the shortest of the three canals Introduction The saccule is a bed of sensory cells situated in the inner ear In the Temporal bone, in the portion beneath the Crista falciformis are three sets of Foramina; one group just below the posterior part of the crest situated in The semicircular canals are three half-circular interconnected tubes located inside each Ear that are the equivalent of three Gyroscopes located in three orthogonal
