The interosseous and lumbrical muscles in twenty-five hands of Japanese adult cadavers were dissected. The palmar and dorsal interosseous muscles continued, with few exceptions, into the wing tendons. The dorsal interosseous muscles gave off tendons which pierced the transverse laminae or passed deep to the transverse laminae, and attached to the bases of the proximal phalanges. The palmar interosseous muscles seldom had such attachments. The palmar and dorsal interosseous muscles sometimes gave off additional tendons which passed superficial to the transverse laminae and attached to the bases of the proximal phalanges. These latter attachments were typical in the contrahentes muscles. Thus, the present findings suggest that the human dorsal interosseous muscles are composite muscles derived from the dorsal abductor, flexor brevis and contrahens muscles, and that the human palmar interosseous muscles are composite muscles derived from the flexor brevis and contrahens muscles. The lumbrical muscles rarely gave off accessory slips with atavistic attachments to the proximal phalanges.
对25具日本成年尸体的25只手的骨间肌和蚓状肌进行了解剖。掌侧和背侧骨间肌除少数例外，均延续至翼状腱。背侧骨间肌发出的肌腱穿过横行纤维层或在横行纤维层深面通过，并附着于近节指骨基底。掌侧骨间肌很少有这种附着。掌侧和背侧骨间肌有时发出额外的肌腱，这些肌腱在横行纤维层浅面通过并附着于近节指骨基底。后一种附着在收缩肌中很典型。因此，目前的研究结果表明，人类背侧骨间肌是由背侧外展肌、短屈肌和收缩肌衍生而来的复合肌，而人类掌侧骨间肌是由短屈肌和收缩肌衍生而来的复合肌。蚓状肌很少发出有返祖附着于近节指骨的副腱。
