Which vein lies on the outermost side of the upper arm?

• A. Basilic Vein
• B. Cephalic Vein
• C. Median Vein
• D. Median Cubital Vein

Answer: (B)

The outermost side of the upper arm is the lateral aspect, where the cephalic vein runs along the outer edge of the arm from the forearm up toward the shoulder and drains into the axillary vein. This makes it the vein you’d identify on the outer surface of the upper arm. The basilic vein sits on the inner (medial) side, and the median cubital vein is the elbow region connector between the cephalic and basilic veins. There isn’t a standard “median vein” as a major upper-arm vessel. So the cephalic vein is the correct choice for the outermost, lateral position.
