title: [Changes in the ultrastructure of neuromuscular synapses in rats under the effects of space flight factors].
abstract: The influence of a 7-day space flight on board the biosputnik "Kosmos-1669" on the neuro-muscular synapses (NMS) of soleus, gastrocnemius and diaphragm muscles distinct in their functions has been studied. The synapse restructuring on the basis of destructive- regenerative process has been discovered. It is manifested to a great extent in the soleus muscle, to a lesser extent in the gastrocnemius muscle and the least of all in the diaphragm muscle. The changes observed in synapses may be caused by the attenuation of their function in weightlessness.
