title: [Dynamics of terminal plaque structure during changes in the impulse activity of sensory endings in the process of their regeneration].
abstract: The dynamics of changes in terminal plates of frog's urinary bladder sensory free visceroceptors during their posttraumatic regeneration was studied. It was shown that during the time period from two months to one year the terminal plate number in receptor bush increased, while their average dimensions decreased and their shape changed. No correlations between the changes of afferent impulse activity and these morphological transformations were found. The data obtained suggest that terminal plates do not seem to participate in the generation of bioelectric activity, but rather appear to be the growth cones of non-myelinated terminal and thus are involved in repair processes.
