Profunda Brachii Artery

The Profunda Brachii artery is the largest branch of the brachial artery. It courses posteriorly in the extensor compartment of the arm, accompanying the radial nerve in the radial groove. It ends by dividing into the middle and radial collateral arteries.

The profunda brachii artery gives rise to multiple collateral branches to provide collateral circulation to the shoulder and elbow joint areas.
