Regarding this, where does the median cubital vein drain blood from?
Venous anatomy of the region The venae comitantes drain into the median cubital vein via a constant branch near the elbow. The superficial forearm veins drain into the cephalic, basilic, and median cubital veins (see Figure 25.3).
Also, what separates the median cubital vein from the median nerve? The median nerve then courses medial to the brachial artery (Figure 3.2). In the cubital fossa, the median nerve lies behind the median cubital vein and under the bicipital aponeurosis, providing a branch to the elbow joint. It is separated from the ulnar artery by the deep or ulnar head of that muscle.
