ELECTRICAL ACTIVITY AND ULTRASTRUCTURE OF BOVINE MESENTERIC LYMPHATICS

Abstract
Membrane action potentials of bovine mesenteric lymphatics were recorded simultaneously with isometric contractions by use of the sucrose gap method. The action potentials always had one-to-one correspondence to the con traction waves. From the effects of tetrodotoxin, manganese, cal-calcium-free environment, and barium chloride on the spontaneous contractions, it was suggested that calcium current may probably play a major role in producing spike discharge in the smooth muscles. Blood capillaries were found within the smooth muscle layers as well as in the adventitia.
