Learn More Course The anterior circumflex humeral artery originates from the lateral aspect of the third part of the axillary artery. It is notably smaller in size than the posterior circumflex artery. After its origin, the anterior circumflex humeral artery passes underneath the coracobrachialis and short head of the biceps brachii. It then wraps around the anterior aspect of the humeral neck. At the intertubercular sulcus of the humerus, it gives rise to an ascending branch which supplies the head of the humerus. It terminates by anastomosing with the posterior circumflex artery.
