Bounded laterally by the brachioradialis muscle and medially by the pronator teres muscle, the fossa contains the tendon of the biceps brachialis muscle and the brachial artery. Two large superficial veins, the cephalic and its branch, the median cubital, are common sites for blood drawing. Synonym: cubital fossa
