[Adrenergic innervation of the extramedullary arteries of the spinal cord of cats].
The adrenergic nerves of the radical and longitudinal arteries and the dura mater at the level of cervical, thoracic and lumbar segments of the ventral and dorsal sides of the spinal cord were studied in 70 mature cats by methods of Falck and Glenner. The adrenergic fibres form developed plexuses different in the density of disposition of nerve conductors on the arteries of different segments of the spinal cord. The adrenergic fibres are also found in the pia mater tissue. Nerve fibres containing active monoaminoxidase are less in number than adrenergic ones found by Falck's method. It is probably due to activation of catecholamines being realized by other ways in addition to oxydative desamination.
