Receptor Sites and Agonist Effects Flashcards
1
Q
Alpha 1
A
Vasoconstriction of arteries and veins
2
Q
Alpha 2
A
Insulin restriction
Glucagon secretion
Inhibition of norepinephrine release
3
Q
Beta-1
A
Positive chronotropic effect
positive inotropic effect
positive dromotropic effect
increased renin secretion for urinary retention
4
Q
Beta-2
A
Bronchiole relaxation Insulin secretion Uterine relaxation Arterial dilation in certain organs Smooth muscle relaxer
5
Q
Dopaminergic
A
Vasodilation of renal and mesenteric arteries
6
Q
Nicotinic
A
Present at neuromuscular junction, allows acetylcholine to stimulate muscle contraction
7
Q
Muscarinic-2
A
Present in the heart; activated by acetylcholine to offset sympathetic stimulation (negative chronotropic effect, negative inotropic effect, negative dromotropic affect)
