title: [Structure of the main and terminal sections of the cholinergic and adrenergic neural plexuses in human skin].
abstract: The dermal neural plexus have been studied in 8 mature persons during the first 6 h after death. The cholinergic neural elements have been revealed by means of Karnovsky -- Roots' method, the adrenergic ones -- by means of incubation in 2% solution of glyoxylic acid. A high acetylcholinesterase activity is displayed in the main dermal neural plexus, from the latter fasciculi of neural fibres go to the blood vessel walls, to the hairy bursae and to the secretory parts of the sweat gland. Together with the parasympathetic neural fibres, sensitive neural fibres are detected in this plexus. The adrenergic neural fibres are mainly found in the terminal neural plexus surrounding the blood vessels, in deep layers of the derma. A suggestion is made that the mediator of the sympathetic plexus gets into the dermal derivatives by the way of diffusion.
