Brachial Artery/Vein

The brachial artery stems from the axillary artery and moves along the humerus (upper arm bone) down to the elbow. It gives rise to the "deep brachial artery" that curves around the back of the humerus to supply blood to the triceps muscles. Shorter branches pass into various other muscles on the front of the upper arm, and others descend down each side of the elbow to join arteries in the forearms. The corresponding brachial vein will parallel the artery on its trip back to the heart.
