The abductor pollicis longus (APL) muscle consists of two separate functional divisions with separate insertions. The muscle is composed of a deep and a superficial division. The APL and the abductor pollicis brevis (APB) are discussed in relation to assessment and clinical conditions on the basis of anatomic and electromyographic studies. It has been found that in some movements of the thumb and the hand, the function of the APL is related to the function of the APB, and vice versa. The APL is an important muscle for the function of the human thumb and hand, and knowledge of its function is important in clinical assessment and reconstructive surgery.
拇长展肌（APL）由两个具有不同止点的独立功能部分组成。该肌肉由深层和浅层部分构成。基于解剖学和肌电图研究，对拇长展肌和拇短展肌（APB）在评估及临床病症方面进行了讨论。研究发现，在拇指和手部的某些运动中，拇长展肌的功能与拇短展肌的功能相关，反之亦然。拇长展肌是人类拇指和手部功能的重要肌肉，了解其功能在临床评估和重建手术中具有重要意义。
