[Degeneration and regeneration of sensory nerve fibers and their endings (receptors)].
After cutting a nerve, inervating a certain part of the body/its nerve fibers and their terminals (receptors) undergo degeneration, which continues several days and proceeds in some of them unevenly quickly. They recover (regenerate) to their normal state and structure several months after the occurred complete destruction of the nervous fibers and terminals. The author describes the results from studies on the inervation of skin transplants and scars in experimental animals and persons to clarify the question about the origin of the regeneration nerve fibers--whether by growth of the central part of the cut nerve or by formation of this part independently in an area. The finding of capsulated receptors--the bodies of Meissner and bulbs with dense vindingsin 2 to 16-years old scars is a sure proof that regenerated nerve fibers and their terminals originate by growth from those cut at the surface of the grafting of the transplant e.g. from the central.
