The vasomotor center (VMC) is a portion of the medulla oblongata[1] that regulates blood pressure and other homeostatic processes. Upon increase in blood carbon dioxide level, it stimulates the sympathetic system to constrict vessels. This is opposite to carbon dioxide in tissues causing vasodilation, especially in the brain.[2][dubious — see talk page] Cranial nerves IX (Glossopharyngeal nerve) and X Vagus nerve both feed into the vasomotor centre and are themselves involved in the regulation of blood pressure.
