The anterior circumflex humeral artery is smaller than the posterior circumflex humeral artery, but is a branch of axillary artery as well.
The anterior circumflex humeral artery emerges from the lateral side of the third part of the axillary artery.
It anastomoses with the posterior circumflex humeral artery after it passes anterior towards the surgical neck of the humerus. The anterior humeral circumflex artery travels horizontally, under the coracobrachialis along with short head of the biceps brachii muscle, in front of the neck of the humerus.
In order to circluate the head of the humerus along with the shoulder-joint; it produces a branch that ascends within the sulcus, after reaching the intertubercular sulcus.
Anterior circumflex humeral artery supplies branches towards the nearby tissues of glenohumeral joint along with the head of the humerus.
