Regeneration of axonal endings of neuromuscular junctions of the soleus muscle in rats under conditions of hypodynamia.

The purpose of the experiments performed was morphometric ultrastructural evaluation of the regeneration of axonal endings after sectioning of nerves in rats kept under conditions of hypodynamia. The investigation indicated a retardation of regeneration of the axonal endings of neuromuscular junctions after denervation of the soleus muscle in rats kept under conditions of hypodynamia as compared with those of the control group. The retarded regeneration of the axonal endings of neuromuscular junctions in experimental animals as compared with that in the control group may be referred to the above mentioned enzymatic and electrolytic disturbances caused by restriction of mobility.
