Abstract
The structure of the triadic junction in frog slow fibers has been studied and compared with that of twitch fibers. The junctional gap is wider (by approximately 13%) in slow fibers. The junctional feet have the same size and disposition as in twitch fibers, although the size and shape of the junctional areas are different. It is concluded that the role of triads in slow fibers is the same as in twitch fibers
摘要
对青蛙慢肌纤维三联体连接的结构进行了研究，并与快肌纤维的结构进行了比较。慢肌纤维中的连接间隙更宽（约宽13%）。连接足的大小和分布与快肌纤维相同，尽管连接区域的大小和形状有所不同。得出的结论是，三联体在慢肌纤维中的作用与在快肌纤维中的作用相同。
