Abstract
The innervation of blood vessels largely determines the functional state of the organ. The aim of the study was to determine the adrenergic innervation of the arteries and veins of the gallbladder in guinea pigs. A fluorescent-histochemical method was applied to total organ preparations. It was found that arteries are most abundantly supplied with adrenergic nerve fibers, which form perivascular adrenergic plexuses around them. Veins contain significantly fewer of these fibers, and perivascular adrenergic plexuses are absent.
