adrenergic pharmacology

Question 1

all adrenergic receptors are what kind of receptors

Answer 1

g protein coupled receptors

Question 2

what type of g protein coupled receptor is alpha1

Answer 2

g q increases calcium concentration increases contraction

Answer 3

gi inhibitory deceases camp

Question 4

what type of g protein coupled receptor is beta 1 2 3

Answer 4

stimulatory increases camp gs

Answer 5

vasoconstriction
increased peripheral resistance
(blood flow)
increased blood pressure
increased closure of bladder spincters
mydriasis- dilation of pupil

Question 6
