Abstract:
Dendrites of type II Dogiel neurons (the local receptors) stained with silver nitrate impregnation by Bilschovsky-Gross method, were analyzed with computer morphometry in cat large intestine. The following parameters have been measured: an area of dendritic receptor field, total area of all receptor elements and total length of all receptor branches. Significant individual variability was noted in the values of these parameters: the maximum value exceeded the minimum one by a factor of 41, 29 and 45, respectively. No correlation between these three parameters has been found. It is suggested that the morphological diversity of dendrites found in this study may serve as a basis of the functional variability of type II Dogiel neurons.
