Abstract：
Muscles and fasciae are mutually connected and are influenced by force transmission. However, the anatomical connectivity and histological features of these structures remain unclear. The aim of this study was to assess the evidence for connection between muscles and deep/muscular fasciae. We assessed this relationship in different topographical regions of human cadavers and in mice. The results showed that myofascial junctions (MFJ) were made up of collagen I immune-positive structures occupying an average area of 5.11 ± 0.81 μm2, distributed in discrete regions at the interface between muscle and fascia with an average density of 9.7 ± 2.51 MFJ/mm and an average inclination angle of 35.25 ± 1.52°. These specialized structures also showed collagen III and HA immunopositivity and the presence of elastic fibers. The human myofascial junction can be visualized, opening emerging insights into the connection between deep/muscular fascia and muscle.
摘要：
肌肉和筋膜相互连接，并受到力传递的影响。然而,这些结构的解剖学连接和组织学特征仍不清楚.这项研究的目的是评估肌肉与深层/肌肉筋膜之间联系的证据。我们在人类尸体和小鼠的不同地形区域中评估了这种关系。结果表明，肌筋膜连接（MFJ）由I型胶原免疫阳性结构组成，平均面积为5.11±0.81μm2，分布在肌肉和筋膜界面的离散区域，平均密度为9.7±2.51MFJ/mm，平均倾角为35.25±1.52°。这些特殊结构还显示了胶原蛋白III和HA的免疫阳性以及弹性纤维的存在。人的肌筋膜连接处可以被可视化,打开新的见解，深/肌肉筋膜和肌肉之间的联系。
