Summary:The ganglia of the plexus myentericus (Auerbach) have their own self-acting vascularization in the form of periganglionic capillary networks. As to the architecture and density, they are quite different from the intramuscular capillary bed. Just as the arterial trunk and arcade vessels, the terminal arterioles and sphincter capillaries running into the periganglionic cappillary network are innervated by noradrenergic axons. Together with periganglionic arteriovenous short circuits, this means favorable prerequisites for a functionally adapted blood supply of the ganglia. The specific arrangement of intramuscular vessels and the plexus Auerbach effects the maintenance of the close topographic and functional relations between both systems in all cases of changes of the shape of the intestinal wall.
