Final answer:
The veins suitable for venipuncture in the antecubital area include the basilic vein, cephalic vein, and median cubital vein. The ulnar vein is not used for venipuncture in this area.
Step-by-step explanation:
In the context of venipuncture, veins that are commonly used in the antecubital area are the basilic vein, cephalic vein, and median cubital vein. These veins are superficial and are often chosen for blood draws due to their accessibility. However, the ulnar vein is not typically used for venipuncture in the antecubital area because it does not course through this region in a manner that makes it suitable for such procedures. While the median antebrachial vein does parallel the ulnar vein, it is the median cubital vein that serves as the most frequent site for drawing venous blood, acting as a link between the cephalic and basilic veins.
