在各种心血管反射中,降压反射通常被认为是最重要的。来自动脉压力感受器的信号通过降压反射调控心脏和血管的活动,从而维持血压的相对稳定。传统认为调节心脏和血管活动的基本中枢在延髓,延髓背外侧为“加压区”,腹内侧为“减压区”。新的资料表明,原来认为延髓背外侧的所谓“ In a variety of cardiovascular reflex, antihypertensive reflex is usually considered the most important. Signals from the arterial baroreceptors regulate heart and blood vessel activity through hypotensive reflexes, thereby maintaining the relative stability of blood pressure. The traditional center of regulation of heart and blood vessels in the medulla oblongata, medullary dorsolateral “pressure zone”, ventral medial “pressure relief zone.” New data show that the medulla oblongata that the so-called "
