Vasoconstriction. One of the first effects is intense vasoconstriction of the skin vessels over the entire body. The posterior hypothalamus strongly activates the sympathetic nervous signals to the skin blood vessels, and intense vasoconstriction occurs throughout the body.
The blood vessels of skeletal muscles, in contrast, has beta 2 receptors which causes vasodilation. Hence sympathetic stimulation cause vasoconstriction of blood vessels of viscera and dilates the vessels of skeletal muscles redirecting blood flow to skeletal system, thus preparing for fight, flight, fright reaction.The heart rate also increases, forcing more blood to flow to muscles.Hope this helps :).ut at the same time they cause vasoconstriction of arteries carrying blood to the digestive organs, kidneys, and all those other internal organs that are not necessary for short-term survival (which is what the sympathetic system is all about).
