The cubital fossa (or antecubital fossa) lies anteriorly to the elbow. Anatomically it is an important triangular area on the anterior view of the human elbow; it is a triangular depression in between the arm and the forearm.
The major contents of the cubital fossa, from lateral to medial are:
M: median nerve
B: brachial artery
T: tendon of biceps
R: radial nerve
P: posterior interosseous branch of radial nerve
