In the left upper limb of an adult male cadaver a triangular muscular slip, 3.5 cm long and 2.5 cm wide, arose from the lower border of latissimus dorsi just proximal to its tendon of insertion. It was inserted by a slender 6 cm long tendon mainly into the coracoid process of the scapula. Three short fibrous strands radiated from this slender tendon to gain attachments to pectoralis minor and the common tendon of origin of the short head of biceps brachii and coracobrachialis. In addition 2 flat tendinous bands attached the margin of this muscular slip to teres major. The thoracodorsal nerve entered the main bulk of latissimus dorsi close to the muscular slip but did not supply a separate branch to the latter. This is an axillary arch muscle in an unusually medial location.
在一具成年男性尸体的左上肢，有一块三角形肌束，长3.5厘米，宽2.5厘米，起自背阔肌下缘，恰在其止腱近端。它通过一条细长的6厘米长肌腱主要止于肩胛骨喙突。三条短纤维束从这条细长肌腱发出，附着于胸小肌以及肱二头肌短头和喙肱肌共同的起始腱。此外，有两条扁平腱性带将这块肌束的边缘与大圆肌相连。胸背神经在靠近这块肌束处进入背阔肌主体，但未向其发出单独分支。这是一块位置异常靠内侧的腋弓肌。
