Local Character of the Veno-Vasomotor Reflex

Abstract

Critical closing pressures were measured as an index of vasomotor tone in the legs of eight rabbits. In seven of these increases in the venous pressure led to definite and consistent increases in critical closing pressure. In all seven preparations the response persisted when all nervous connections to the rest of the animal were destroyed. This increase in vasomotor tone in response to increased venous pressure is probably due to a local veno-vasomotor reflex.
