glossopharyngeal ganglion

The group of neuron cell bodies associated with the ninth cranial nerve. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the glossopharyngeal ganglion is

The group of neuron cell bodies associated with the ninth cranial nerve. The atlas records it as a nerve at the organ scale in the human body.

Where the glossopharyngeal ganglion is

It sits in the head, within the nervous system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the glossopharyngeal ganglion connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. a kind of epibranchial ganglion.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the glossopharyngeal 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 ganglion of glossopharyngeal nerve, ganglion of glosspharyngeal nerve, glossopharyngeal IX ganglion, petrosal ganglion and gIX. Searching any of those names reaches this page.

Questions

Where is the glossopharyngeal ganglion?

It sits in the head, within the nervous system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the glossopharyngeal ganglion connect to?

A kind of: epibranchial ganglion.

Is the glossopharyngeal 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.
