[The intramural neural apparatus of the mesenteric lymphangion of the small intestine].

Concentration of nerve structures in the lymphangion wall directly correlates with myocyte number in its different regions. Maximal adrenergic and cholinergic fibres concentration was defined in valvular torus muscular cuff of the lymphangion and minimal--in the valvular sinus wall. Besides, as structural organization of adrenergic plexus does not differ from that of antichollinaestherase-positive one and electron microscopic photos display diverse cholinergic and monoaminergic mediator vesicles in same fibres a suggestion is made on the mixed mediator nature of intramural plexuses of the lymphangion.
