Forma la cara medial de la eminencia tenar y se describe como compuesta por una parte superficial y otra profunda (aunque el tamaño de la parte profunda es variable). Inserciones: se origina en el tubérculo del trapecio y en el retináculo flexor asociado. Se inserta en la base de la falange proximal del pulgar.
