Cubital fossa

From Wikilectures

[edit] Boundaries of the cubital fossa

• superior – biceps brachii muscle
• medial (ulnar) - pronator teres muscle
• lateral (radial) - brachioradialis muscle
• superficial boundary (roof)- deep fascia reinforced by the bicipital aponeurosis (a sheet of tendon-like material that branches off the tendon of the biceps)
• deep boundary (floor)- brachialis (and supinator) muscles

[edit] Contents

• The radial nerve (between brachioradialis and brachialis)
• The brachial artery (bifurcates into the radial artery (superficial) and ulnar artery (deeper)) and the brachial vein
• The median nerve
• The cubital lymph nodes

• one can also use the mnemonic for lateral to medial: "Really Need Beer To Be At My Nicest". (radial n., bicipital tendon, brachial a., median n.)

The ulnar nerve is also in the area, but is not in the cubital fossa; it occupies a groove on the posterior aspect of the medial epicondyle of the humerus. Several veins are also in the area (for example, the median cubital vein, cephalic vein, and basilic vein) but these are usually considered superficial to the cubital fossa, and not part of its contents.
