The artery and the posterior circumflex humeral artery most often arise as a common trunk from the lateral side of the third part of the axillary artery at the level of the distal border of subscapularis. They soon divide, the anterior artery running horizontally deep the coracobrachialis and the short head of biceps brachii and anterior to the surgical neck of humerus. At the intertubercular sulcus it gives off an ascending branch whilst continuing laterally beneath deltoid and the long head of biceps to end by anastamosis with the posterior circumflex humeral artery.
