Study on the innervation of the pancreas of the rat.
The pancreas of the adult rat is examined by the silver impregnation method. The intrapancreatic nerves form the following three plexuses: periacinous, periinsular and perivascular; anastomosing fibers are presented between the three plexuses. Sympathetic ganglia as well as parasympathetic nerve cells are met with in association and in close proximity to the islet tissue. The significance of the double innervation of the islet tissue is discussed.
