Median cubital vein (also known as the cubital vein of the forearm) It is a superficial vein that is most usually utilised for venipuncture because it rests above the cubital fossa and acts as an anastomosis between the cephalic and basilic veins. It is a branch vein of the basilic vein that branches out from the basilic vein. Secondly, there is the cephalic vein. It may be traced proximally until it empties into the axillary vein, which is shown in both the forearm and the arm.
