Correct answer: ABrachial artery

The bicipital aponeurosis is a fascial sheet extending from the biceps tendon medially across the antecubital fossa. It provides a degree of protection to the underlying brachial artery (and median nerve) during venepuncture of the median cubital vein. Despite this protection accidental arterial puncture remains a recognised complication.
