What is the opposite side of the elbow called?

The opposite side of the elbow is called the antecubital space, the cubital fossa or the chelidon. Some people call it the "elbow pit," which is intended to echo the word "armpit."

The superficial veins that cross through this area (the basilic vein, the cephalic vein and the median cubital vein) make it an ideal spot for a physician to draw a patient's blood, to place a stethoscope while measuring blood pressure or to palpate for a brachial pulse. This part of the human anatomy also contains the radial nerve, the biceps brachii tendon, the brachial artery and the median nerve.
