Final answer:
In the antecubital area from lateral to medial, one would find the cephalic vein, the median cubital vein commonly used for blood draws, the basilic vein, and the median antebrachial vein.
Step-by-step explanation:
The contents of the antecubital area from lateral to medial include several important veins. Laterally, we begin with the cephalic vein, which is significant for draining the hand and digits leading to the radial vein. Moving medially, we find the median cubital vein, a superficial vessel that connects the cephalic and basilic veins and is often used as a site for venous blood draws.
Medially adjacent to the median cubital vein is the basilic vein, which continues through the arm medially and superficially to the axillary vein. Lastly, parallel and medial to the basilic vein is the median antebrachial vein, which intersects with the median cubital vein and parallels the ulnar vein, leading to the upper arm where it continues with the brachial vein towards the axillary vein.
