Abstract

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.
