Innervation of the intestinal wall. Both sympathetic and cholinergic nerves innervate the intestinal wall, where they synapse with the enteric nervous system (ENS). Only the sympathetic nerve fibers reach the mucosal layer of the intestine, where they can interact with immune cells. The ChAT+ T-cells reside in the intestinal wall, possibly contributing to immunological homeostasis. Mϕ—macrophages; NE—norepinephrine; ACh—acetylcholine.
