Anatomical terminology [ edit on Wikidata]

The anterior humeral circumflex artery (anterior circumflex artery, anterior circumflex humeral artery) is an artery in the arm. It is one of two circumflexing arteries that branch from the axillary artery, the other being the posterior humeral circumflex artery. The anterior humeral circumflex artery is considerably smaller than the posterior and arises nearly opposite to it,^{[ citation needed ]} from the lateral side of the axillary artery. ^[1]

Anatomy

Course and relations

The anterior humeral circumflex artery passes horizontally posterior to the coracobrachialis muscle and short head of the biceps brachii muscle, in and anterior to of the surgical neck of the humerus. Upon reaching the intertubercular sulcus, it gives off an ascending branch ^[1] which ascends along the sulcus^{[ citation needed ]} to supply the head of the humerus and the shoulder-joint. It continues laterally, deep to the long head of the biceps brachii and the deltoideus muscle, before anastomosing with the posterior humeral circumflex artery. ^[1]
