摘　　要：目的分析和描述肱二头肌近端起源部位的形态学特点,并测量其肌腱的解剖学数据,为肱二头肌的相关临床应用提供参考。方法在6侧成人肩部标本上(左4具,右2具)解剖观察肱二头肌短头肌腱的起源、形态、走行以及其与喙肱肌、肌皮神经等结构的毗邻关系,并测量肱二头肌短头肌腱长度、宽度和厚度。结果肱二头肌短头前表面覆以一层较厚的腱膜,腱膜下为肌性结构并以肌纤维直接起源于喙突尖,而不是一般意义上的腱性结构。肱二头肌短头肌腱的长度、宽度和厚度分别为(107.7±9.6)mm,(20.0±1.5)mm和(5.8±2.0)mm。结论肱二头肌短头是以肌纤维直接起于喙突。Objective To analyze and describe the morphological characteristics of the proximal origin of the biceps brachii,and measure the anatomical data of its tendons,so as to provide references for related clinical applications of the biceps brachii.Methods Six adult shoulder specimens(4 on the left and 2 on the right)were dissected to observe the origin,morphology,and course of the biceps brachii tendon and its adjacent relationship with the coracobrachialis muscle,musculocutaneous nerve and other structures.And then the length,width,and thickness of the biceps tendon were measured.Results The origin of the short head of biceps consisted of muscle fibers attaching directly to the tip of the coracoid process,with a thin,tendinous aponeurosis covering its anterior surface,rather than a true tendon as previously described.The mean of length,widths and thickness of the short head of biceps were(107.7±9.6)mm,(20.0±1.5)mm and(5.8±2.0)mm.Conclusion The short head of the biceps brachii is directly from the coracoid process with muscle fibers.
