Regional differences in histochemical properties along the length of rat intrafusal muscle fibers were examined. Outside the muscle spindle capsule the nuclear bagfibers lose their hitherto characteristic ATPase activity and stain in a manner similar to that of extrafusal type I muscle fibers, perhaps in relationship to spindle skeletofusimotor innervation.
研究了大鼠肌梭内肌纤维全长组织化学特性的区域差异。在肌梭囊外,核袋纤维失去了其迄今特有的ATP酶活性,染色方式与梭外I型肌纤维相似,这可能与肌梭骨骼肌梭运动神经支配有关。
