title: Neural control of blood flow in gastric mucosa.
abstract: The innervation of the small vessels in the fundic mucosa of the rat and the effects of vagotomy on this innervation were studied ultrastructurally. The capillaries and arterioles, but not the venules, were found to receive direct innervation. Vagotomy causes degeneration of the nerve endings that innervate these vessels, confirming their vagal origin. This finding, and the fact that some morphologic changes in the capillaries were observed after vagotomy, provides morphologic evidence for the neural control of blood flow in the rodent gastric mucosa.
