Clara Franzini-Armstrong (2011) CIL:36089, damselfly, flight muscle cell. CIL. Dataset

The image shows the surface of the ribbon-like myofibrils, with some remnants of the SR attached mostly at the Z lines. The regular disposition of attached cross bridges is visible in many areas. Most images of this group show fractures through the outer membrane of mitochondria and SR/T tubules of dyads nestled in long grooves of the mitochondrial surface. All leaflets of the membranes appear in the images.

该图像展示了带状肌原纤维的表面，其中部分横纹肌附着物主要位于Z线附近。在许多区域中，可见附着横桥的规则排列。本组中的多数图像均展示了通过线粒体外膜及双联的SR/T管状结构，这些结构位于线粒体表面的长沟中发生的断裂。图像中清晰可见所有膜瓣。
