| Abstract: | The functional and morphological organization of stomach vegetative innervation was studied. It is shown, that the sympathetic nerve strengthens vagal stimulation of motor activity of various departments of a stomach. In realization of the phenomenon participate preganglionic serotoninergic fibres transmitting excitation on ganglionic serotoninergic neurons. It is established, that stimulation of a wandering nerve results to degranulation of serotoninergic EC-cells carrying on the surface ganglionic 5-HT3,4-receptors. The irritation of a wandering nerve results in reduction of volume of EC-cells in older age. |
