Final answer:
Yes, the basilic vein is the least anchored vein while the median cubital vein is the most commonly used for drawing venous blood.
Step-by-step explanation:
Yes, it is true that the basilic vein is the least anchored vein while the median cubital vein is the most commonly used.
The basilic vein is a superficial vein of the arm that arises from the palmar venous arches, intersects with the median cubital vein, parallels the ulnar vein, and continues into the upper arm.
On the other hand, the median cubital vein is a superficial vessel located in the antecubital region that links the cephalic vein to the basilic vein in the form of a v, and it is frequently used for drawing venous blood in humans.
