question about ephinephrine

Members don't see this ad.

the book says that epinephrine causes constriction in arterioles in skin but dilation in leg muscle.
In this case can I say epinephrine cause both vasoconstriction and vasodilation?

i suppose so. Epi causes vasoconsriction to areas in the body that it "shuts off," and increases blood to parts of the body involved in "flight or fight."

Put it this way: if you're running away from some man eating beast, would you want your blood to flow to your skin or your legs?

yup it depends on the receptors that it binds to
