Which vein is located along the midline of the forearm?

• A. Median antebrachial vein
• B. Cephalic vein
• C. Basilic vein
• D. Median cubital vein

Answer: (A)

The main idea is the arrangement of the superficial forearm veins. The vein that runs along the midline of the forearm is the median antebrachial vein. It travels up the center of the anterior forearm and typically drains into the basilic vein or connects with the median cubital vein near the elbow. In contrast, the cephalic vein runs along the lateral (thumb-side) aspect of the forearm, the basilic vein runs along the medial (ulnar) side, and the median cubital vein crosses the cubital fossa at the elbow, linking the cephalic and basilic veins rather than traveling down the midline. Therefore, the vein located along the midline is the median antebrachial vein.
