Deep Brachial Artery

Tuesday, September 13, 2011

The deep brachial artery is an upper branch of the brachial artery that supplies the deltoid and triceps brachii muscles and the shaft of the humerus. Closely associated with the medial nerve, the deep brachial artery originates from the lateral-posterior part of the brachial artery; then it runs down obliquely along and across the humerus bone, giving off the radial collateral and medial collateral arteries. The deep brachial artery is also known as the arteria profunda brachii artery.
