Cubital fossa
The cubital fossa is the triangular area on the anterior view of the elbow joint of the arm. Additional recommended knowledge
BoundariesThe boundaries of the cubital fossa include the following:
ContentsThe cubital fossa contains three main vertical structures (from lateral to medial):
When the radial nerve is included, one can also use the mnemonic for lateral to medial: "Really Need Beer To Be At My Nicest".[2] When the radial nerve is excluded, one can use the mnemonic TAN, for "Tendon Artery Nerve". 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. Clinical aspectsDuring blood pressure measurements, the stethoscope is placed over the brachial artery in the cubital fossa. The cubital fossa is also an area used to palpate for the brachial pulse. The area just superficial to the cubital fossa is often used for venous access (phlebotomy). A number of superficial veins can cross this region. Historically, back when (venous) blood-letting was practiced, the bicipital aponeurosis (the ceiling of the cubital fossa) was known as the "grace of God" tendon because it protected the contents of the fossa (i.e. the brachial artery and the median nerve).
