对血压的调节目前,认为动物血压水平的高低取决于多种心血管反射的整合结果。如防御警觉反应与化学感受性反射有互相加强并升高血压的作用。压力感受性反射与心内机械感受性反射,则与之相拮抗而有降低血压的作用。血压水平就取决于这些反射、反应的动态平衡。而延髓头端腹外侧区(rVLM)很可能是延髓心血管中枢的所在地。 (一)VLM的形态学研究 The regulation of blood pressure At present, the level of animal blood pressure that the level depends on the integration of a variety of cardiovascular reflex results. Such as defense alert response and chemoreceptors have to strengthen each other and increase blood pressure. Pressure-sensitive reflex and intra-cardiac mechanical reflex, then antagonistic with the role of lowering blood pressure. The level of blood pressure depends on these reflections, the dynamic balance of the reaction. The rostral ventrolateral medulla (rVLM) is probably the location of the medullary cardiovascular center. (A) Morphology of VLM
