Posterior humeral circumflex
Introduction
Overview
Overview
The posterior humeral circumflex artery (posterior circumflex artery, posterior circumflex humeral artery) arises from the axillary artery at the lower border of the Subscapularis, and runs backward with the axillary nerve through the quadrangular space.
It winds around the neck of the humerus and is distributed to the Deltoideus and shoulder-joint, anastomosing with the anterior humeral circumflex and profunda brachii.
