从系统发育上来说，腱组织首先作为肌隔膜出现在无脊椎动物脊索动物文昌鱼中。这种胶原纤维的二维阵列是高度组织化的，纤维沿着两个主轴延伸。在盲鳗中，出现了第一个线性肌腱，并且肌隔膜已经发育出具有单向纤维取向的特殊区域——肌隔膜平板内的线性肌腱。肌腱对压缩载荷的反应首先形成纤维软骨垫，并在严重应力下形成籽骨。这种对负载做出反应的能力的证据首先出现在软骨鱼中，这里记录的是来自硬质猎物压碎黄貂鱼下巴的肌腱。籽骨常见于硬骨鱼和四足动物中。某些鸟类的肌腱在拉伸载荷作用下也会钙化，而这种对载荷的反应在其他脊椎动物中是看不到的。我们的结论是，肌腱的进化史使我们深入了解使用模型系统来研究肌腱生物学。使用哺乳动物和鱼类模型可能比鸟类模型更合适，因为鸟类对拉伸载荷的新反应明显进化。 (C) 2002 Elsevier Science Inc. 保留所有权利。
Phylogenetically, tendinous tissue first appears in the invertebrate chordate Branchiostoma as myosepta. This two-dimensional array of collagen fibers is highly organized, with fibers running along two primary axes. In hagfish the first linear tendons appear and the myosepta have developed specialized regions with unidirectional fiber orientation-a linear tendon within the flat sheet of myoseptum. Tendons react to compressive load by first forming a fibrocartilaginous pad, and under severe stress, sesamoid bones. Evidence for this ability to react to load first arises in the cartilaginous fish, here documented in a tendon from the jaw of a hard-prey crushing stingray. Sesamoid bones are common in bony fish and also in tetrapods. Tendons will also calcify under tensile loads in some groups of birds, and this reaction to load is seen in no other vertebrates. We conclude that the evolutionary history of tendon gives us insight into the use of model systems for investigating tendon biology. Using mammal and fish models may be more appropriate than avian models because of the apparent evolution of a novel reaction to tensile loads in birds. (C) 2002 Elsevier Science Inc.
