Question 1

What are the sympathetic Adrenergic receptor sub types of the blood vessels, what is the effect?

Answer 1

alpha 1, alpha 2 = constriction

beta-2 = dilation

Question 2

What are the sympathetic Adrenergic receptor sub types of the heart, what is the effect?

Answer 2

beta 1 = tachycardia (rapid heart rate), increased contractility
alpha-1 = increased contractility

Question 3

What are the sympathetic Adrenergic receptor sub types of the bronchi, what is the effect?

Answer 3

beta-2 = relaxation

Question 4

What are the sympathetic Adrenergic receptor sub types of the thrombocytes, what is the effect?

Answer 4

alpha 2 = aggregation

Question 5

What are the sympathetic Adrenergic receptor sub types of the kidneys, what is the effect?

Answer 5

alpha 1 and alpha 2 = vasoconstriction
beta 1 = renin release
beta 2 - vasodilation

Question 6

What are the sympathetic Adrenergic receptor sub types of the adipocytes what is the effect?

Answer 6

alpha 2 = inhibition of lipolysis

beta 1, 2, 3 = lipolysis

Question 7

CVS

Where do baroceptors and chemoreceptors input to?

Answer 7

-Hypothalamus
-Nucleus ambigus dorsal vagal nerve
(then affects cardiac ganglia and the heart)

beta-receptors = increase HR and contractility
