人类右前臂显示出正中动脉的持续存在以及正中神经和手掌循环的异常。正中神经形成包围正中动脉的环，在前臂发出第3掌指支，并具有高掌皮神经起源和双鱼际供应。掌浅弓不完整。正中动脉伸入手部，提供第二掌指总动脉和食指桡侧动脉。它与第一腹腔中的桡动脉吻合。
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.
