Veins transporting blood from the upper limbs are classified into deep and superficial categories. The ulnar and radial veins are the two prominent deep veins. The ulnar vein drains the fingers via the superficial palmer venous arches, while the radial vein drains the palms via the deep palmer venous arches. These veins then merge to form the brachial vein. The superficial venous system begins with a plexus of many small veins in the dorsum of the hand. These smaller veins drain into two prominent superficial veins, the cephalic and basilic veins in the forearms. Additionally, the medial antebrachial vein also joins either the cephalic or brachial vein. The medial cubital vein at the elbow connects the cephalic and brachial veins. The basilic vein travels along the forearm and joins the brachial vein. Together, they form the axillary vein. The cephalic vein also joins the axillary vein at the shoulder. Lastly, the axillary vein transitions into the subclavian vein, emptying into the brachiocephalic branch of the superior vena cava.
