Accessory belly of the first lumbrical – a case report

Out of the 20 cadavers allotted for first MBBS students dissection we focused our study on the intrinsic muscles of the hand. All the intrinsic muscles in the hands of the female cadavers were as usual. However, we observed an additional slip of origin of the first lumbrical in one hand out of the 36 hands from male cadavers examined.
