我们分析了一级激光衍射线的微观结构，从静止和强直收缩的单肌纤维从青蛙胫骨前肌肌节长度的分布是连续的或离散的。测量平行放置的相邻微结构元素之间的距离，我们绘制了肌节长度的相应差异的直方图。从静息和收缩纤维获得的直方图在约12-14 nm处具有显著峰。结果表明，肌节长度分布可能是离散的，单位间距约为12-14 nm。
We analyzed the microstructure in the first-order laser diffraction line from both resting and tetanically contracting single twitch fibers from frog anterior tibial muscle to see if the distribution of sarcomere lengths is continuous or discrete. Measuring the distance between adjacent microstructural elements lying parallel, we plotted a histogram of the corresponding differences of sarcomere length. The histograms obtained both from resting and contracting fibers had a prominent peak at approximately 12–14 nm. The result suggests that the sarcomere length distribution may be discrete with unit separation of approximately 12–14-nm sarcomere length.
