Anterior Aspect of the Forearm and Cubital Fossa Ural Verimli M.D. Assistant Professor of Anatomy Marmara University School of Medicine Superficial veins of the forearm Cephalic vein Basilic vein Median cubital vein Median vein of forearm Superficial veins of the forearm Deltopectoral groove Flexor and Extensor Retinaculum Muscles of the Anterior Forearm Superficial Compartment -Pronator teres muscle -Flexor carpi radialis muscle - Palmaris longus muscle -Flexor carpi ulnaris muscle Middle Compartment -Flexor digitorum superficialis Deep Compartment -Flexor digitorum profundus -Flexor policis longus -Pronotor quadratus Superficial Compartment -Pronator teres muscle -Flexor carpi radialis muscle - Palmaris longus muscle -Flexor carpi ulnaris muscle Pronator teres O: Ulnar head →medial border of coronoid proc. Humeral head → upper part of medial epicondyle, CFT, antebrachial fascia I: anterior surface of radius F: Pronation, weak flexion of forearm Flexor carpi radialis O: medial epicondyle, CFT, antebrachial fascia I: Base of 1st and 2nd metacarpal F: Flexion and abduction of the wrist N: Median nerve Palmaris longus O: medial epicondyle, antebrachial fascia I: Flexor retinaculum, palmar aponeurosis F: Flexion of the wrist and stretches the palmar aponeurosis N: Median nerve Flexor carpi ulnaris O: humeral head → medial epicondyle Ulnar head → medial border of ulna, olecranon I: Pisiform, 5th metacarpal bone F: Flexion and adduction of the wrist N: Ulnar nerve Middle Compartment Flexor digitorum superficialis O: humeroulnar head → medial epicondyle, CFT, anterior surface of ulnar colateral ligament Radial head → anterior surface of radius I: sides of the medial 4 middle phalanx F: Flexion the proximal phalanx N: Median nerve Flexor digitorum profundus O: anterior and medial surface of ulna, interosseus membrane I: base of the medial 4 distal phalanx F: Flexion of the distal phalanx N: Lateral →Median nerve Medial → Ulnar nerve Flexor policis longus O:, interosseus membrane, anterior surface of radius I: base of the distal phalanx of thumb F: Flexion of the distal phalanx of the thum N: Median nerve Pronator quadratus O: Lower part of ulna I: Lower part of ulna F: Pronates the forearm N: Median nerve Cubital fossa Triangular fossa in front of the elbow joint medial→ pronator teres Lateral → brachioradialis muscle Base → line passing through the epicondyle Apex → where the lateral and medial borders meet Floor → supinator and brachialis muscle Cubital fossa Content of the cubital fossa 1.
