Flight muscles, insects

Figure 9. A schematic representation of crossbridge orientation assumed from electron micrographs of insect flight muscle in relaxed and rigor states by Reedy et al. (1965). The crossbridge is thought to have an orientation of 90° to the thick filament axis in the relaxed state and an orientation of 45° to the thick filament axis in rigor.

Synchrotron Radiation Studies on Insect Flight Muscle... 

The development of synchrotron radiation as a source for x-ray diffraction and the investigation of the structure and contractile mechanism of insect flight muscle have had a symbiotic relationship since the early 1970 s. While it is perhaps true that, until a few years ago, synchrotrcm radiation research had benefitted more from this than insect flight muscle research, recent time-resolved work has begun to fulfill the promise of those first diffraction experiments carried out by Rosenbaum et al. (1971) in 1970. 

Fiuther progress in time resolved experiments will need increased x-ray intensity and smaller beam sizes, particularly for measurement of the weaker reflections from insect flight muscle. Fortunately, both of these improvements are expected over the next few years from new storage ring sources, from wigglers and undulators and from...

The first detailed experiments to be reported which involved the use of synchrotron radiation on insect flight muscle fibres were concerned with an examination of the effects of ATP-analogues on their structure (Goody et al., 1975). This work was done...
