Balance nerve

Nervus vestibularis

The balance nerve conveys sensory impressions from the vestibular labyrinth in the temporal bone. The nerve exits the temporal bone through the inner auditory canal where the vestibular ganglia is located. The ganglia contains the bipolar cell bodies of the vestibular nerve fibers. The nerve fibre bundle continues into the brainstem on the border between the medulla and the bridge. A larger part of the filamentous mass finds its way directly into the vestibular nuclei. The remaining nerve fibers divide, each into a branch that enters the vestibular nuclei and a branch that enters the cerebellum via the lower cerebellar arm where the branches end as moss filaments and contact grain cells , primarily in the nodulus cortex.
