The role of the vasomotor center of the medulla oblongata in controlling blood flow; baroreflexes, chemoreflexes, and medullary ischemic reflex. Introduction: The vasoconstriction and vasodilation are collectively called as vasomotion. The narrowing of the vessel is called as vasoconstriction, and it occurs by contraction of smooth muscle in the tunica media. The widening of the vessel in vasodilation is by muscular passivity rather than muscular effort. The smooth muscles get relaxed, and the blood pressure allows the vessel to expand. The vasomotor center of the brain controls the vasomotion.
