Depressor reflex

Japanese: 減圧反射 - げんあつはんしゃ（英語表記）depressor reflex

A reflex phenomenon in which stimulation of nerves or receptors automatically causes the dilation of the arterioles in the vascular beds throughout the body, especially in the internal organs (kidneys, spleen, etc.), via the cardio-vasomotor center, resulting in a decrease in arterial blood pressure. This reflex was first discovered in 1866 when Zion IFTsion and C. Ludwig stimulated the aortic nerve, resulting in a decrease in heart rate and low blood pressure, and for this reason the aortic nerve is also known as the decompression nerve. A similar reflex can also be caused by electrical stimulation of the carotid sinus nerve.

Japanese:

神経あるいは受容器の刺激によって，自動的に心･血管運動中枢を介して身体の広範な血管床，とくに内臓(腎臓，脾臓等)の細動脈が拡張し，動脈血圧が下降する反射現象。この反射は，古く1866年，ツィオンI.F.TsionとルートウィヒC.Ludwigが大動脈神経を刺激したさい心拍数の減少と低血圧が発生したことから知られ，そのため大動脈神経を別名減圧神経ともいう。同様の反射は頸動脈洞神経の電気刺激によっても起こる。
