Clara Franzini-Armstrong (2011) CIL:36090, 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.

图像呈现了类似带状肌原纤维的表面，其中一些肌节横管（SR）的残留部分主要附着在Z线附近。在多个区域中，可见附着横桥的规则排列。本组大部分图像展示了穿过线粒体外膜及位于线粒体表面长沟中的二联管SR/T管的断裂。图像中清晰可见所有膜瓣。
