Left inferior ulnar collateral artery

Looks like

A small branch leaving the brachial artery a few centimetres above the elbow, passing in front of the inner elbow bump.

What it does

Feeds nearby muscle and joins the network of arteries around the elbow joint.

Keeping it well

Rarely a problem by itself; its connections keep the forearm alive when the brachial artery is injured just above them.
