STUDIES ON THE RECEPTOR AREAS AND THE NERVOUS PATHWAY OF THE BEZOLD-JARISCH REFLEX IN DOGS: WITH REFERENCE TO THE PRESSOREFLEX ARISING FROM THE LEFT CORONARY ARTERY.

Abstract

The left coronary perfusion technique was applied in the study of the Bezold-Jarisch reflex in dogs, with special reference to the coronary pressoreflex which had been previously described by Okinaka et al. The present findings indicate that the receptors of the coronary pressoreflex differ in location from those of the Bezold-Jarisch reflex, and the anterior ventricular nerves participate as the afferent pathway in both reflexes. The efferent cardio-inhibitory fibers of the Bezold-Jarisch reflex were found to run through the AH-rootlets apart from the afferent fibers in the main trunk of the vagus nerve.
