Which vein is the deeper vein of the arm that forms from the radial and ulnar veins and leads to the axillary vein?

• A. Brachial vein
• B. Cephalic vein
• C. Basilic vein
• D. Subclavian vein

Answer: (A)

The main idea is how the deep venous drainage of the arm is organized. The deep veins run with the arteries and collect blood from the forearm via the radial and ulnar veins. Those two veins unite to form the brachial vein. The brachial vein then travels up the arm and drains into the axillary vein, which is the next segment as you move proximally. The superficial veins, like the cephalic and basilic, are on the surface and aren’t formed from the radial and ulnar veins. So the vein formed from the radial and ulnar veins and that leads to the axillary vein is the brachial vein.
