Diversity of cross-bridge configurations in invertebrate muscles.
X-ray diffraction patterns from relaxed invertebrate muscles reveal the thick filament symmetries and cross-bridge configurations. The cross bridges are substantially angled to the filament axes. The results on symmetry are generally consistent with Squire's model.
