Page 1 of 65
, Page|2
Drugs that turn off PNS -- ANSWER--Muscarinic antagonists
(parasympatholytic drugs, antimuscarinic drugs, muscarinic blockers,
anticholinergic drugs)
Muscarinic antagonists function -- ANSWER--selectively block the effects
acetylcholine at muscarinic receptors
Muscarinic antagonists are also known as -- ANSWER--parasympatholytic
drugs, antimuscarinic drugs, muscarinic blockers or anticholinergic drugs
Alpha 1 receptor functions -- ANSWER--
vasoconstriction ejaculation contraction of
bladder neck & prostate
Alpha 2 receptor function -- ANSWER--little clinical significance
Beta 1 receptor functions -- ANSWER--Heart (increase rate and force of
contraction)
Kidney (renin release)
Conduction of the AV node
, 3
Beta 2 receptor functions -- ANSWER--Bronchial
dilation relaxation of uterine muscle vasodilation
glycogenolysis
Cholinergic receptor subtypes -- ANSWER--nicotinic and muscarinic
Adrenergic receptor subtypes -- ANSWER--alpha 1, alpha 2, beta 1, beta 2
What are the neurotransmitters of the PNS -- ANSWER--Acetylcholine
(mediates cholinergic receptors)
Norepinephrine/epinephrine (mediate adrenergic receptors)
Dopamine function -- ANSWER--dilates renal blood vessels
Without subtypes -- ANSWER--a drug that acts on one site will alter all sites
Cholinergic drugs function to -- ANSWER--Turn on PNS
Page 3 of 65

Muscarinic Agonists function -- ANSWER--mimic the effects of acetylcholine
at muscarinic receptors
Atropine function -- ANSWER--
Increases HR Decrease secretions relax
bronchi decrease tone of detrusor
decrease tone & motility of GI
mydriasis (pupil dilation)
Atropine uses -- ANSWER--
preanesthetic eye disorders
