Receptor Sites (Alpha and Beta)

Question 1

Alpha 1

Answer 1

blood vessels: vasoconstriction (increase bp)
eyes: mydriasis (dilation)
bladder: relax
prostrate: contract

Question 2

Alpha 2

Answer 2

blood vessels: decrease bp (inhibit norepi)
smooth muscle (GI): decrease tone and motility

inhibits norepinephrine, acetylcholine, and insulin

Question 3

Beta 1

Answer 3

heart: increase HR and contraction
kidney: renin release = increase bp

Question 4

Beta 2

Answer 4

vasodilation
bronchodilation
glycogenolysis (liver and muscle)
glucagon release
relax uterus smooth muscle
