[Cholinergic and adrenergic innervation of the microvessels of serous membranes].
The morphological substrate of double (sympathetic and parasympathetic) innervation of the vessels of the microcirculatory bed of serous coat was studied in cats. The architectonics of both components of the vasomotor innervation in the pericardium, the pleura and the peritoneum was examined by histochemical methods used for revealing the cholinergic (Koelle-Gomori) and the adrenergic (Falck-Hillarp) neutral structures. the quantitative predominance of the elements of adrenergic innervation over the cholinergic ones was revealed in the identical portions of the arterial bed. Vegetative innervation of the terminal arteries and capillaries was unsteady in character and proved to be essentially confined to single synaptic contacts arising along the course of adrenergic and cholinergic terminals. Vegetative innervation of the venous supply including the postcapillary venules and small collecting veins was extremely poor and frequently not found at all.
