M3 activation on the lungs causes bronchoconstriction or bronchodilation?
bronchoconstriction
B2 activation on the lungs causes bronchoconstriction or bronchodilation
bronchodilation
Methacholine is what kind of drug?
M3 agonist, thus causing bronchoconstriction
Ipratropium, tiotropium,, glycopyrrolate are what type of drug?

Stimulation of the M3 receptor would have what effect on the GI system?
It would induce SM contraction thus promoting digestion
Stimulation of the B2 receptor would have what effect on the GI system?
It would induce SM relaxation thus inhibting digestion

M3 antagonists, thus reducing peristalsis
Stimulation of the M3 receptor has what effect on saliva?
Causes watery saliva secretion
Stimulation of the B2 has what effect on saliva?
Thick saliva secretion
Pilocarpine is what kind of drug?
M3 agonist, thus promoting watery saliva secretion
Glycopyrrolate is what kind of drug?
M3 antagonist, thus causing THICK saliva secretion
Stimulation of the a1 receptor has what effect on the eyes?
Affects the Dilator muscle, thus causing smooth muscle contraction leading to more light in the eyes
Stimulation of the M3 receptor has what effect on the eyes?
Affects the constrictor muscle, thus causing contraction of the constrictor muscle leading to less light in the eyes
Atropine is what kind of drug? and effects the eyes how?
M3 antagonists, thus leading to pupil dilation (inhibits the constrictor muscle)
Carbachol is what kind of drug? and has what effect on the eyes
M3 agaonist, thus promoting pupil constriction via constrictor muscle
Stimulation of M3 has what effect on the uterus?
Induces contractions
Stimulation of B2 has what effect on the uterus?
Causes relaxation
Terbutaline is what kind of drug?
B2 agonist, thus causing uterine relaxation. Can be used to prolong pregnancy if baby is coming out too early
Midronine affects vasculature in what mechanism?
a1 agonist, thus increasing BP (vasoconstriction)
Prazosin, terazosin, doxazosin affect vasculature in what mechanism?
a1 antagonist, thus decreasing BP (vasodilation)
