[The local sensory neurons of the small intestine in the turtle (an intravital study)].

Morphological statics and dynamics of living sensory neurons and their dendrites were studied by means of automatic television image analyser in steppe turtle small intestine. Values of quantitative characteristics (squares of the terminal plaques and neuron body receptor zone, summary square of dendritic elements and specific density of the receptor innervations zone were obtained. Dynamics of terminal receptor plaques mechanical mobility was qualitatively characterized. Significant heterogeneity of local sensory neutrons and their dendrites structural organisation was demonstrated. Polymorphism was suggested to be the expression of sensory neurons functional heterogeneity.
