Axillary Artery

Thursday, August 4, 2011

The axillary artery is a continuation of the subclavian artery, arising from the lateral border of the first rib. It carries oxygenated blood and supplies the arm, becoming the brachial artery once it gets into the upper arm (after traveling by the lower margin of the teres major muscle). Running parallel to the axillary vein along its length, the axillary artery gives the following branches: 1) superior thoracic artery; 2) thoracoacromial; 3) lateral thoracic; 4) subscapular; 5) anterior humeral circumflex; and 6) posterior humeral circumflex artery.
