[Morphologic changes in the nervous apparatus of the pharynx, esophagus and stomach of cats following a single gravitational stress].
Under investigation were the pharynx, oesophagus and stomach of 23 cats subjected to a single maximum endurable gravitation stress. The material was treated after Bielschowski-Gross. It has been established that as early as within 48--72 hours after gravitation effects there appear changes of different elements of the nervous apparatus of the organ under study such as increased argirophilia of nervous structures and reactive changes of different sensory nerve terminations. Motor animal nerve terminations do not change. Most of myelinated afferent fibres and non myelinated vegetative fibres undergo reactive changes. Within 7 days there appear certain myelinated fibres which are in the stage of granular desintegration,
