[Adrenergic--sympathetic nervous apparatus of the cerebral arteries and its role in regulating cerebral circulation].
By means of fluorescence microscopy of catecholamines the authors studied the adrenergic innervation of cerebral arteries in mammals (dogs, cats, rabbits). It was demonstrated that the basis of a sympathic nervous apparatus of pial arteries in all animals is a well developed adrenergic plexus. In different calibre arteries of the pial membrane the nervous plexus differs significantly in its structure and degree of saturation of nerve fibers. Besides, in the points of artery branches and sometimes just along the vessels there are peculiar structures consisting of circular windings of adrenergic nerve fibres. In this connection the authors discuss histophysiological organization of the adrenergic component of pial arteries through which the sympathic nervous systems exerts influence on the functional state of the cerebral arteries and cerebral circulation.
