large branch arising from the posteromedial aspect of the brachial artery in the proximal upper arm distal to teres major muscle. Follows the radial nerve closely. Passes posterolaterally to supply the deep and posterior musculature of the upper arm. Also supplies the nutrient artery and the deltoid artery. Divides distally into the radial collateral artery and the middle collateral branch of arteria profunda brachii. Also known as the deep brachial artery.
