The four dorsalmuscles
The four dorsalmuscles (mm. interossei dorsales)are abductors; they converge toward the third metacarpal bone and attach to the index, middle and ring fingers. The thumb and the little finger have their own abductors. All interosseous muscles, in addition, flex the proxinmal phalanx and extend the middle and distal phalanges wormlike. Thus, each phalanx of teach finger has one of even two separate muscles moving it; for example, the proximal phalanx of each finger is flexed by the lumbrical and the palmar interosseous musclesICD 10 Coding is very useful service as it will help in the collections and also for the amount that is pending from the payers and patients
