[Characteristics of the interrelationships of gliocytes with neurocyte processes in rat celiac ganglia].

While studying the ultrastructure of rat celiac nodes, it was stated that lemmocytes from the intercellular plexus develop around separate neuronal processes spiral membranes and multilayer membranes in the shape of concentric "musses". Similar membranes but of simpler structure develop perisomatic glyocytes. In old rats these types of glial membranes occur considerably rare. Both varieties of complicated types of glial membranes serve, evidently, for the isolation of preterminal sections of neuronal processes from probable unwanted contacts with other terminals.
