[The structure of the initial inputs into the metasympathetic nervous system of the rat uterus].

Different populations of sympathetic neurons exerting modulating influence on neurons of nervous plexuses of proper metasympathetic nervous system of the uterus in albino laboratory rats were detected using the method on retrograde transport of fluorescent marker primulin. Following the injection of the marker into uterovaginal plexus, labelled neurons were found as aggregations in caudal mesenterial sympathetic ganglia, ganglia of coeliac plexus, renal ganglia and ganglia of coeliac trunk. The structure of nervous paths of external control of uterus functioning was analysed.
