median nerve

A nerve of the arm that originates from the brachial plexus and is formed from parts of the medial and lateral cords of the brachial plexus, and continues down the arm to enter the forearm with the brachial artery. It originates from the brachial plexus with roots from C5, C6, C7, C8 & T1. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the median nerve is

A nerve of the arm that originates from the brachial plexus and is formed from parts of the medial and lateral cords of the brachial plexus, and continues down the arm to enter the forearm with the brachial artery. It originates from the brachial plexus with roots from C5, C6, C7, C8 & T1. The atlas records it as a nerve at the organ scale in the human body.

Where the median nerve is

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

What the median nerve connects to

The atlas records 12 typed relationships for it, across 6 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 median 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 medianus. Searching any of those names reaches this page.

Questions

Where is the median nerve?

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

What does the median nerve connect to?

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

Is the median 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.
