Palmaris longus contributes to the anteposition and pronation of the thumb under circumstances. It is however restricted by its medial tendon which runs into the palmar aponeurosis. The diversion of this tendon and the mobilisation of the muscular head of the abductor pollicis brevis arising from its lateral tendon will substantially accentuate the rôle of palmaris longus as a muscle of the thumb.
掌长肌在某些情况下有助于拇指的前位和旋前。然而，它受到进入掌腱膜的内侧肌腱的限制。该肌腱的转向以及由其外侧肌腱产生的拇短展肌肌头的活动将大大增强掌长肌作为拇指肌肉的作用。
