During the superficial dissection of the pectoral region and the arm, an abnormal biceps brachii muscle was observed unilaterally. This muscle had three heads. Whereas the short and long heads had their normal origin, the accessory head originated from the anterior surface of the distal part of the pectoralis major muscle, which formed the anterior axillary fold. To our knowledge, this variation has not been previously described. Innervation and vascular supply of this accessory head was from the musculocutaneous nerve and the brachial artery, respectively.
在对胸区和手臂进行浅部解剖时，单侧观察到一块异常的肱二头肌。该肌肉有三个头。短头和长头的起点正常，而副头起自胸大肌远端的前表面，该表面形成了腋前襞。据我们所知，这种变异此前尚未有过描述。该副头的神经支配和血管供应分别来自肌皮神经和肱动脉。
