Upper Extremity Arteries

Upper Extremity Arteries

Subclavian Arteries

On the right side of the body, the subclavian arises from the innominate artery and supplies the right side of the neck and head and the right shoulder and arm.

On the left side of the body, the subclavian arises directly from the arch of aorta supplies the left side of the neck and head and the left shoulder and arm.

Axillary Artery

A continuation of the subclavian artery beginning at the lateral border of the first rib.

Brachial Artery

A continuation of the axillary artery beginning at the lower margin of the teres major muscle.  It continues down the anterior aspect of the arm until reaches the cubital fossa (bend of the elbow) where it bifurcates into the radial and ulnar arteries.

Radial Artery

The radial artery arises from the bifurcation of the brachial artery and travels down the lateral aspect (thumb side) of the forearm.

Ulnar Artery

The ulnar artery arises from the bifurcation of the brachial artery and travels down the medial aspect of the forearm.
