Brachial Artery

The brachial artery is the upper arm main blood vessel which carries oxygenated blood that supplies the arm. It arises from the axilliary artery beyond the lower margin of the teres major muscle, traveling down the ventral surface of the arm, all the way down to the cubital fossa at the elbow. Then, the brachial artery branches into the radial and ulnar arteries which continue down the forearm.

Along its course, the brachial artery gives off three smaller branches: the deep brachial artery, superior ulnar collateral artery, and inferior ulnar collateral artery.
