The superficial volar (Palmar) arch and the arteries contributing to its formation are highly variable. The arch is usually formed by the superficial branch of the ulnar artery and completed by one of the branches of radial artery, that is, the superficial palmar branch, arteria princepspollicis or arteria radialisindicis. It is rarely completed by the axis artery of the upper limb, that is, median artery which accompanies the median nerve. Fifty formalin-fixed upper extremities from of unknown sex were dissected and the superficial volar arch was observed. Thirty five(70%) hands showed complete superficial volar arch which was completed mainly by superficial branch of radial artery and in three cases it was completed by the median artery. Fifteen(30%) hands showed incomplete volar arch. Since the superficial volar arch is the main source of arterial supply to the palm, the details about its possible variations is important for the reconstructive hand surgeons.
