O - flexor retinaculum and tubercle of trapezium I - radial side of first metacarpal | Opponens pollicis |
Performs the action of thumb opposition by bringing the thumb across the palm | Opponens pollicis |
O - medial epicondyle I - flexor retinaculum and palmar aponeurosis | Palmaris longus |
Tenses the palmar fascia Flexes wrist Flexes elbow | Palmaris longus |
