MORPHOMETRIC AND HISTOCHEMICAL CHARACTERISTIC OF CLUSTER ORGANIZATION OF THE NEURONS OF RAT SPINAL NERVE SENSORY GANGLION AND OF SYMPATHETIC TRUNK CERVICOTHORACIC GANGLION
The topographic pattern of neurons in spinal nerve sensory ganglion and of sympathetic trunk cervicothoracic ganglion was investigated at adult rats (n=12). Results of the work have shown, that these organs are characterized by a heterogeneity of the neurons according to their morphometric (Nissl's stain) and histochemical (acetylcholinestherase and NADPH-diaphorase activity) parameters. The common feature of ganglia organization was demonstrated by the clustered pattern of neuron topography. Clusters were formed on a principle of heterogeneity, uniting from 3-4 to 9-10 neurons. The application of a combined histochemical method has allowed to identify the histo-functional charactristics of neurons within the clusters of the ganglia studied, which were also detected by standard histological methods.
