The Cubital Fossa or Elbow Pit is the triangular area on the anterior view of the elbow of a humans. The Cubital Fossa is corresponding or homologous to the popliteal fossa of the lower limb. It is a triangular hollow in front of the elbow.
In the article, we will discuss the Cubital Fossa Mnemonics but before it lets looks briefly the content of Cubital Fossa from medial to lateral side.
Contents Of Cubital Fossa:
From Medial to Lateral:
- Median Nerve: It leaves the fossa by passing between 2 heads of pronator teres.
- Brachial Artery: It ends in the fossa in the level of neck of radius by splitting into radial and ulnar arteries.
The radial artery is superficial and makes the fossa in the apex. The ulnar artery is deep and enters deep to the pronator teres.
- Biceps Tendon: It enters backwards and laterally to be connected on the radial tuberosity.
- Radial nerve: It is located in the gap between brachialis medially and brachioradialis laterally. At the level of lateral epicondyle it breaks up into 2 terminal branches: (a) superficial radial nerve and (b) deep radial nerve.The latter vanishes in the substance of supinator muscle. The superficial radial nerve enters downwards under the cover of brachioradialis.
- Posterior interosseous branch of radial nerve: The posterior interosseous nerve, also known as the dorsal interosseous nerve, is the continuation of the deep branch of the radial nerve after it penetrates the supinator muscle
Cubital Fossa Mnemonic:
A useful mnemonic to remember the contents of the Cubital Fossa is, from medial to lateral:
“My Brother Throws Rad Parties”
M for Median Nerve.
B for Brachial Artery.
T for Tendon of Biceps.
R for Radial Nerve.
P for Posterior Interosseous branch of Radial nerve.
