颈动脉窦和主动脉弓压力感受器反射在心输出量、外周阻力和血量等发生突然变化的情况下 ,对动脉血压进行快速的调节起重要的作用 ,是动脉血压维持稳态的重要神经反射机制。当动脉血压突然升高时 ,反射性引起心迷走神经紧张加强 ,心交感神经紧张和交感神经缩血管紧张减弱 ,导致?
Carotid sinus and aortic arch baroreceptor reflex in the cardiac output, peripheral resistance and sudden changes in blood circumstances, the rapid adjustment of arterial blood pressure plays an important role in the maintenance of arterial blood pressure is an important neurological reflex mechanism. When the sudden increase in arterial blood pressure, reflex caused by increased vagal nerve vagusia, cardiac sympathetic nervous and sympathetic vasoconstriction weakened, resulting in?
