Cholinergic innervation of pig pancreas.

Pancreases from 5 sexually mature sows were used in this investigation. In order to detect cholinergic fibers in the pancreas, the method of Karnovsky and Roots (1964) was applied. It was shown that cholinergic nerve fibers occur in the whole organ as perivascular plexuses, interlobular nerves, perilobular and periinsular plexuses. The existence of individual cholinergic neurons in the pig pancreas also has been stated.
