- The vascular motor center appropriately maintains the autonomic center of vascular motor nerve tension and is also the center of vascular motor reflexes.
- The main center is located in the diamond-shaped fossa of the Yannao. This center in Yannao can be divided into a vasoconstriction center and a vasoconstriction center that antagonizes the vasoconstriction center. However, the former is known mainly. When this part or below is damaged, blood vessels in the body dilate and blood pressure drops. However, soon after the spinal asomotor center, which is located in the spinal cord, gains autonomy. The blood vessel tension and blood pressure can return to normal within a few days. Under conditions of CO2 accumulation and O2 deficiency in the blood or insufficient blood supply to the central site (cerebral anemia). Increased tension in the main center increases blood pressure, thereby mobilizing and expelling the blood stored in the internal organs of the abdomen, and at the same time promoting breathing and removing metabolic disorders from gas. As the center of vascular motion reflex. Accept a variety of afferent stimuli. Or it is affected by the higher centers of the cerebral cortex and mesencephalon. Increase blood pressure during emotional excitement and stress. It is closely related to the thermoregulatory center and is also affected by the respiratory center.
