The Role of Neural Reflexes in Control of the Cardiovascular System during Stress.

Abstract

The inhibitory influence of vagal afferents on the cardiovascular systems was determined in studies with anesthetized cats and conscious dogs. Results indicate that vagal afferents exert a tonic influence on vasopressin release in conscious dogs. It was also found that these afferents may play a keen role in the regulation of renin scretoary rate during conditions which may alter cardiopulmonary blood volume. A number of studies illustrated the importance of cardiac vagal receptors in the regulation of vascular resistance and the inotropic state of the heart. Data also indicated that cardiac vagal receptors may serve as part of a negative feedback system to regulate sympathetic outflow to the heart. (Author)
