Anatomical knowledge of variation of cutaneous supply of hand is required to the anesthetist to give local anesthesia and to the surgeon for various operations around wrist. The present case was reportedto enlighten the knowledge of anatomists as well as to the clinicians. During routine dissection of 70 year old male cadaver a rare variation of distribution of posterior interosseous nerve on dorsum of hand of right side was observed. The adjacent sides of index and middle fingers supplied by posterior interosseous nerve. Cutaneous nerve supply of thumb and lateral side of index finger was by three proper digital branches from superficial division of radial nerve and rest was supplied by ulnar nerve. Anatomical knowledge of this variation willbe useful to anaesthetists and surgeons during various operations.

Supernumerary muscles are an infrequent fmding during dissections around the ankle. This report focusses on the finding of one such muscle which was found in the tarsal tunnel of the left lower limb unilaterally during routine dissection of a 70 year old male cadaver in Bankura Sammilani Medical College, West Bengal.This supernumerary muscle had a single head of origin from the flexor hallucis longus and posterior intermuscular septum and was traced to its insertion into the flexor digitorum accessorius in the sole and hence was named flexor digitorum accessorius longus, and its relations with the neurovascular bundle were noted. Flexor digitorum accessorius longus may be a cause of tarsal tunnel syndrome so it should be kept in mind during its management. It may also produce symptoms mimicking soft tissue tumors. Thus knowledge of this muscle will be of utmost importance to anatomists, clinicians, radiologists and athletes.
