title: Adrenergic nerve innervation of the human cutaneous glomus.
abstract: Adrenergic (monoaminergic) nerve innervation of cutaneous glomus from the human thumb was examined by the fluorescence method of Falck and Hillarp for the demonstration of monoamines. The main anastomotic vessel (Suquet-Hoyer canal) was found to possess a pattern specific for nerve innervation. The Suquet-Hoyer canal was surrounded like a sheath by numerous thin adrenergic fibers, which were distributed like threads around a bobbin. These nerve fibers are superimposed directly on the outer surface of the glomus cell layer, not penetrating between these cells. They show varicose axon ramifications.
