Study Notes
Cubital Fossa
- Located on the anterior aspect of the elbow joint, forming the transition between the arm and the forearm
- An inverted triangular, fat-filled depression
Boundaries
- Superior: the line joining the medial and lateral humeral epicondyles (epicondylar line)
- Lateral: medial border of brachioradialis
- Medial: lateral border of pronator teres
- Apex: formed by the meeting of the lateral and medial boundaries (proximal intersection of the brachioradialis and pronator teres)
- Roof: deep fascia of forearm reinforced medially by the bicipital aponeurosis
- Floor: brachialis muscle (medial), and supinator muscle (lateral)
Contents
- Median nerve
- Brachial artery and brachial veins (venae comitantes)
- Tendon of biceps
- Radial nerve
- Posterior interosseous branch of radial nerve
Significance
- Anatomically important as it serves as a passageway for vascular and nervous structures passing between the upper arm and forearm
