[Nervous apparatus of the 8th pair of cranial nerves after exposure to gravitation loading].

Neural apparatus of epineurium, perineurium and endoneurium of the cat vestibulocochlear nerve was studied by methods of Rasskazova, Bielshowsky--Gross, Kampos, Kuprianov, Gomori, Falck in modification of Chilingarian, Koelle--Gomori, Falck--Hillarp--Govyrin. A single gravitation loading effect was stated to produce reactive, and sometimes destructive changes in the sensitive nervous structures of the intraorganic apparatus of the neural sheaths. The greatest and earliest changes (the first day) were noted in the neural apparatus of epineurium of the vestibulocochlear nerve, the least and latest (the third day) -- in endoneurium.
