Chapter 12 ANS Flashcards
what is the primary neurotransmitter for the PSNS
Acetylcholine
what are the receptors of the PSNS called
muscarinic and Nicotinic
what do muscarinic receptors stimulate
stimulates smooth muscle and slows HR
what do nicotinic receptors stimulate
stimulates skeletal muscles
what is the main neurotransmitter in the SNS
norepinephrine
what are the receptors of the SNS called
Alpha 1 & 2
Beta 1 & 2
what do Alpha 1 receptors do
affect peripheral blood vessels pupils and bladder
what do Alpha 2 receptors do
inhibits neurotransmitter release
what do Beta 1 receptors do
Affect the heart and kidney
what do Beta 2 receptors do
affect smooth muscle of the lungs and uterus
what is physostigmine used for**
It is an antidote for anticholinergic poisoning which is common result of exposure to to much pesticide
what are the signs and symptoms of cholinergic medication toxicity
SLUDGE
Salvation
Lacrimation (tears)
Urinary incontinence
Diarrhea
Gastrointestinal cramps
Emesis (vomiting)
what are some common uses of cholinergic medications
Neurogenic bladder (urinary incontinence)
Glaucoma
Myasthenia gravis (condition where there is weakness in the muscles)
Alzheimer’s
Why should you not take two cholinergic drugs together ***
because cholinergic drugs can have an additive effect which can lead to toxicity
what is a major side effect of B agonists
cardiac arrhythmia
