glossopharyngeal nerve

Cranial nerve that branches into the ramus communicans (to the skin), the pretrematic (to the walls of the pharynx and mouth, viscero-sensory fibers), and the larval post-trematic branch (lost in the adult). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the glossopharyngeal nerve is

Cranial nerve that branches into the ramus communicans (to the skin), the pretrematic (to the walls of the pharynx and mouth, viscero-sensory fibers), and the larval post-trematic branch (lost in the adult). The atlas records it as a nerve at the organ scale in the human body.

Where the glossopharyngeal nerve is

It sits in the head, within the nervous system. Positioned deliberately as part of this species body plan.

What the glossopharyngeal nerve connects to

The atlas records 11 typed relationships for it, across 6 kinds of connection. part of gustatory system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the glossopharyngeal nerve. 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

Questions

Where is the glossopharyngeal nerve?

It sits in the head, within the nervous system. Positioned deliberately as part of this species body plan.

What does the glossopharyngeal nerve connect to?

Part of: gustatory system.

Is the glossopharyngeal nerve 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.
