vagus nerve

Cranial nerve that branches into the lateral (to body sense organs) and the intestino-accessorial (to the skin, muscles of shoulder, hyoid, larynx, gut, lungs, and heart). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the vagus nerve is

Cranial nerve that branches into the lateral (to body sense organs) and the intestino-accessorial (to the skin, muscles of shoulder, hyoid, larynx, gut, lungs, and heart). The atlas records it as a nerve at the organ scale in the human body.

Where the vagus nerve is

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

What the vagus nerve connects to

The atlas records 22 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 vagus 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

Also recorded as 10n, nervus vagus [x], tenth cranial nerve, vagus, vagus X nerve and vagus nerve [X], and 8 more. Searching any of those names reaches this page.

Questions

Where is the vagus nerve?

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

What does the vagus nerve connect to?

Part of: gustatory system.

Is the vagus 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.
