Abstract
The structural organization of the adrenergic (sympathetic) component of the autonomic innervation of the depressor zone of the cat aortic arch was studied by luminescence microscopy of the catecholamines. A terminal adrenergic plexus, branching extensively in the connective-tissue basis of the depressor area of the aortic arch, was discovered. The participation of vessels supplying blood to the depressor area was established. Adrenergic neurons were found in the territory of the depressor zone of the aortic arch. It is postulated that the adrenergic component of the depressor zone of the aortic arch participates in the peripheral mechanism of the regulatory effects of the sympathetic nervous system on the baroreceptor apparatus.
