[Gradient of serotonergic innervation of internal organs].

The unidirectional synergistic effect of the vegetative nervous system departments was studied at the regulation of the activity of internal organs. It was shown that the sympathetic nerve intensification of the vagal stimulation of EMA of stomach, urinary bladder, ureters, uteruss, fallopian tubes and deferent duct is realized by means of activation of serotonergic fibrae preganglionares that transmit the activation to 5-NTS,4 serotonin receptors of intramural ganglia that, in their turn, activate 5-NT1,2 serotonin receptors of effector cells.
