Abstract
1. The relationship between intra-aortic pressure and rate of efferent discharge in the hepatic branch of the splanchnic nerve, and release of glucose from the liver was studied in toad in vivo.
2. The inverse relationship between intra-aortic pressure and efferent discharge rate in the hepatic nerve as well as amount of glucose release from the liver was observed.
3. The existence of a blood sugar control mechanism due to the baroreceptor reflex through sympathetic innervation of the liver was suggested.
