23. X-ray Picture of Relaxed and Contracting Muscle a b Low-angle X-ray diffraction patterns from ( a ) relaxed and ( b ) active molluscan smooth muscle (anterior byssus retractor muscle from Mytilus edulis ). The actin pattern in ( a ) shows a clear third layer line but a missing second layer line, whereas ( b ) shows a second layer line (2) almost as strong as the third (3). From Vibert et al. [3].
