vestibular ganglion

The ganglion of the vestibular nerve. It contains the cell bodies of the bipolar primary afferent neurons whose peripheral processes form synaptic contact with hair cells of the vestibular sensory end organs[WP,unvetted]. Distributed to the maculae of the utricle and saccule and to the ampullary crests of the semicircular ducts. The vestibular fibers arise in bipolar cells in the vestibular ganglion in the internal acoustic meatus. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the vestibular ganglion is

The ganglion of the vestibular nerve. It contains the cell bodies of the bipolar primary afferent neurons whose peripheral processes form synaptic contact with hair cells of the vestibular sensory end organs[WP,unvetted]. Distributed to the maculae of the utricle and saccule and to the ampullary crests of the semicircular ducts. The vestibular fibers arise in bipolar cells in the vestibular ganglion in the internal acoustic meatus. The atlas records it as a nerve at the organ scale in the human body.

Where the vestibular ganglion is

It sits in the head, within the nervous and sensory systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the vestibular ganglion connects to

The atlas records 9 typed relationships for it, across 4 kinds of connection. part of vestibular labyrinth, vestibular system and vestibulo-auditory system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the vestibular ganglion. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as Scarpa's ganglion, vestibular part of vestibulocochlear ganglion, vestibulocochlear VIII ganglion vestibular component, nucleus nervi oculomotorii, pars medialis and vestibulocochlear ganglion vestibular component. Searching any of those names reaches this page.

Questions

Where is the vestibular ganglion?

It sits in the head, within the nervous and sensory systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the vestibular ganglion connect to?

Part of: vestibular labyrinth, vestibular system and vestibulo-auditory system.

Is the vestibular ganglion the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
