title: [Ultrastructure of spindles in m. soleus of rats after repeated simulation of the weightlessness effects].
abstract: Postponed for a long time repeated simulation of the weightlessness effects in rats by tail-suspension increases in the amount of intrafusal muscle fibers in m. soleus spindles, reflecting presumably elevation of the sensitivity of mechanoreceptors.
