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.'
