Posterior Humeral Circumflex Artery

Friday, September 16, 2011

The posterior humeral circumflex artery is an oxygen-rich blood vessel which originates from the axillary artery in the shoulder, and supplies the deltoid muscle and upper part of the humerus bone. It winds around the back of the humerus, traveling posteriorly as it follows the axilliary nerve. The posterior humeral circumflex artery anastomoses with the anterior circumflex and the deep brachial arteries.
