What is the cubital fossa
A triangular depression in front of the elbow joint.
Pulse/artery medial to the tendon of biceps brachii in the cubital fossa
The brachial artery
Base of the cubital fossa
Between the two epicondyles of the humerus
Medial border of the cubital fossa
Pronator Teres muscle
Lateral border of the cubital fossa
The medial border Brachioradialis muscle
Floor of the cubital fossa
Formed proximally by the brachialis and distally by the supinator muscle
Roof of cubital fossa
Skin and fascia reinforced by the bicipital aponeurosis.
Contents of the cubital fossa
The radial nerve
Biceps tendon
Brachial artery
Median Nerve
Radial nerve in the cubital fossa
Passing underneath the brachioradialis muscle. As it does so, it divides into its deep and superficial branches
Biceps tendon
Runs through the cubital fossa attaching to the radial tuberosity just distal to the neck of the radius
Median nerve
Leaves the cubital between the two heads of pronator teres.
Common site for venepuncture
The median cubital vein (superficial) and connects the basilic and cephalic veins.
