[Structural and functional reactive changes in the bushy interceptor of the frog urinary bladder upon adequate stimulation].
Morphological and functional changes in the bushy receptors of the frog urinary bladder were studied after a definite cystectasia (bladder wall distention). Morphological and electrophysiological parameters were registered synchronously. Under the effect of distention the total rate of afferent impulse activity was demonstrated to increase with a simultaneous increase of the average size of the receptor end-plates and with changing (growing round) in their form. Increment of the average size of the end-plates overtakes that of the distance between two points chosen on the urinary bladder wall; certain shifts are also observed in time parameters for staining the receptors with methylene blue. A possibility is suggested on interconnections of morphological and electrophysiological shifts.
