ulnar nerve

A nerve which runs near the ulna bone. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ulnar nerve is

A nerve which runs near the ulna bone. The atlas records it as a nerve at the organ scale in the human body.

Where the ulnar nerve is

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

What the ulnar nerve connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of arm, brachial nerve plexus and forelimb, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the ulnar 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 nervus ulnaris. Searching any of those names reaches this page.

Questions

Where is the ulnar nerve?

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

What does the ulnar nerve connect to?

Part of: arm, brachial nerve plexus, forelimb and limb.

Is the ulnar 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.
