[Innervation of the mucosa of the small intestine of laboratory animals. I. Architecture, light microscopic structure and histochemical differentiation].
1. The small intestine mucosa has a dense and differentiated innervation. The most dense nerve plexuses are contained in the villi. Each tubular gland is surrounded by a rope-ladder-like plexus, mostly developed in the lower and upper third. 2. According to our observations most of the axons in the mucosa are cholinergic. Cholinergic and adrenergic axons take part in the innervation of the glands. Moreover enterochromaffine cells can be innervated for instance sympathetically. Intraepithelial axons could not be found.
