| Abstract: | The body of sensory neurons in the frog spinal ganglion++ possesses an active mobility. This is demonstrated as pulsation and changes in its form. The mobility is closely connected with electrogenesis of cells. When an irritation is applied (press of a needle, or application of acetylcholine on the urinary bladder receptors), the neurons of the node respond with an increasing rate of impulse activity. Simultaneously, the mobility of these neurons increases. The character and form of their mobility in response to mechano- and chemoirritation differ from each other. Possible mechanisms of connection between the form of the cell body mobility and the character (active or passive) of its electrogenesis are considered. The mobility of the neurons, together with other morphological signs (tinctorial peculiarities and some others) can serve as an indication of their functional state without application of electrodes in morphological experiments. |
