hypoglossal nerve

Cranial nerve that innervates the muscles of the tongue. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the hypoglossal nerve is

Cranial nerve that innervates the muscles of the tongue. The atlas records it as a nerve at the organ scale in the human body.

Where the hypoglossal nerve is

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

What the hypoglossal nerve connects to

The atlas records 14 typed relationships for it, across 4 kinds of connection. a kind of cranial nerve.

Supply and innervation

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

Questions

Where is the hypoglossal nerve?

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

What does the hypoglossal nerve connect to?

A kind of: cranial nerve.

Is the hypoglossal 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.
