The muscle-tendon junction of murine skeletal muscles has been analyzed by a variety of extraction techniques, by myosin subfragment-1 binding experiments, and by ultrastructural immunocytochemistry. The results indicate that the muscle-tendon junction is composed of four distinct domains: an intracellular domain, the internal lamina; a domain connecting the internal lamina with the lamina densa of the external lamina, the connecting domain; the lamina densa; and a domain which attaches the lamina densa to the collagen fibers, the matrix. Each of these domains is distinct with respect to position, three-dimensional organization, and molecular composition, and is therefore considered to have a unique role in the transmission of contractile force.
通过多种提取技术、肌球蛋白亚片段-1结合实验以及超微结构免疫细胞化学方法，对小鼠骨骼肌的肌腱连接部位进行了分析。结果表明，肌腱连接部位由四个不同的区域组成：细胞内区域，即内板层；连接内板层与外板层致密层的区域，即连接区域；致密层；以及将致密层附着于胶原纤维的区域，即基质。这些区域在位置、三维结构和分子组成方面各不相同，因此被认为在收缩力的传递中具有独特作用。
