[Morphometric characteristics of rat viscero- and somatosensory neurocytes of the caudal ganglia in the vagus nerve].
In experiments performed in 63 adult albino male rats, the participation of afferent neurons of caudal vagal ganglion in the innervation of different organs was investigated. Horseradish peroxidase and conjugate of horseradish peroxidase with wheat germ agglutinin were used as the tracers. Metric parameters (diameter of an equivalent circle) and shape parameters (circular factor of the form) of marked neurocytes were studied using computer videoanalysis method. The dependence of neuronal cell body dimensions on the distance to the innervated target organ was established. The exclusion was represented by the neurocytes, innervating the root of the tongue, which are larger than those projecting to the pancreas. The reason for these discrepancies seems to be associated with the differences of viscero- and somatosensory relations.
