Anatomy and Function of the Vestibular Ganglion - The vestibular ganglion is where the superior and inferior divisions of the vestibular nerve meet. - It merges with the cochlear nerve to form the vestibulocochlear nerve (cranial nerve VIII). - The ganglion contains the cell bodies of bipolar neurons. - The peripheral processes of these neurons form synaptic contact with hair cells of the vestibular sensory end organs. - These sensory end organs include the cristae ampullaris of the semicircular duct and the maculae of the utricle and saccule.

Development of the Vestibular Ganglion - The ganglion is a critical part of neurogenesis in the inner ear. - It is established from the otic placode during embryonic development. - Auditory and vestibular neurons segregate into the medial spiral ganglion and lateral vestibular ganglion. - The differentiation between auditory and vestibular neurons occurs early in development. - The ganglion reaches its final size by the end of gestation. - The vestibular ganglion is named after Italian anatomist and surgeon Antonio Scarpa. - Scarpa detailed the anatomy of the structure and surrounding structures of the inner ear. - The ganglion was described in Scarpa's 1789 note 'De structura fenestrae rotundae auris, et de tympano secundario.'
