title: Histochemistry of intrafusal muscle fibers outside the spindle capsule.
abstract: 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.
