Abstract
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. Most of the axons in the mucosa are cholinergic. Cholinergic and adrenergic axons take part in the innervation of the glands. Enterochromaffin cells can be innervated sympathetically. Intraepithelial axons could not be found.
