Middle collateral branch of deep brachial artery

Looks like

The other end branch of the deep brachial artery, running down the back of the arm inside the triceps.

What it does

Supplies the triceps and joins arteries around the back of the elbow (the olecranon).

Keeping it well

Of interest mainly to surgeons; its links help keep the elbow region supplied when a main artery is blocked.
