Cubital Fossa Floor

The floor of the cubital fossa is formed proximally by the brachialis and distally by the supinator muscle.

Cubital fossa floor.

The radial nerve is in the vicinity of the cubital fossa located between brachioradialis and brachialis muscles. Floor of cubital fossa muscles. The cubital fossa is triangular in shape and thus has three borders. It is also known as the antecubital because it lies anteriorly to the elbow.

The floor of the fossa is formed by the brachialis muscle proximally and the supinator muscle distally the roof from superficial to deep forms from the skin fascia and the bicipital aponeurosis. The cubital fossa contains four main vertical structures from lateral to medial. It is a space filled with different structures that makes up its content. Lateral border medial border of the brachioradialis muscle.

Medial border lateral border of the pronator teres muscle. The cubital fossa is a triangular shaped depression located between the forearm and the arm on the anterior surface of the elbow with the apex of the triangle pointing distally. Deep boundary floor brachialis and supinator muscles. The cubital fossa is a triangular depression located in front of the anterior elbow the medial border is formed by the pronator teres which arises from the medial epicondyle of the humerus the lateral border is formed by the brachioradialis muscle which arises from the lateral supracondylar ridge of the humerus the meeting of these 2 muscles.

Superior border hypothetical line between the epicondyles of the humerus. It has three boundaries borders and it also has a floor.
