RESUMO

A right human forearm showed persistence of the median artery in combination with anomalies of the median nerve and of the palmar circulation. The median nerve formed a ring enclosing the median artery, gave off its 3rd palmar digital branch in the forearm, and had a high palmar cutaneous nerve origin and a double thenar supply. The superficial palmar arch was incomplete. The median artery extended into the hand, providing the 2nd common palmar digital artery and the artery to the radial side of the index finger. It anastomosed with the radial artery in the 1st web space.
