[Study of the innervation of blood vessels of the digestive organs by fluorescence microscopy].
The blood vessels of the samll intestine and the gallbladder were shown to possess a great amount of adrenergic nerve fibres which, when penetrating the thickness of the wall of the above organs, become thinner and the distributed between the tissue structures of the organs as the thinnest monoaxonal network. The method of Falck--Hillarp--Krokhina was used. Among the vessel nerves there are perivascular nerves accompanying the vessels along their total legnth, juxtavascular and intramural nervous bundles of the sumpathetic nature detected by the fluorescent-microscopy method. Large arteries are disposed in a considerably thicker network of specifically fluorescing fibres than veins and small arteries.
