Autonomic nervous system consists of...
Sympathetic(adrenergic) and Parasympathetic(cholinergic) Nervous System
What are some actions of the Sympathetic NS..
dialates pupils, inhibits flow of saliva, accelerates heart beat, dilates bronchi, inhibits peristalsis and secretion of stomach, conversion of glycogen to glucose, secretion of adrenaline and noreadrenaline, inhibits bladder contraction
What are some actions of the Parasympathetic NS..
constricts pupil; stimulates flow of saliva; vagus nerve:( slows heart beat, constricts bronchi, stimulates parastalsis and secretion, stimulates release of bile); contracts bladder
Preganglionic fibers of the Sympathetic NS is .... and the preganglionic fibers of the Parasympathetic are ...
Innervations of autonomic regulation are .... with each other.
complimentary; i.e. in male reproduction, the erection of the penis is parasympathetic(calmness) and ejaculation is sympathetic(excite).
Parasympathetic dominates the activity of ...and sympathetic dominates the activity of ...
rest and digest;
Sympathetic nervous system functions are...
1. regulation of cardiovascular
2. regulation of body temp
3. fight or flight
Innervations and control of the autonomic regulation has three parts...
1. have opposite effect
2. both compliment each other
3. innervation by only one division
Autonomic feedback is ...
the process of self adjustment such as the baroreceptor reflex(receptors on large arteries [aorta/carotid sinus]that respond to increases or decreases in BP)
Sympathetic NS initiates responses at ... site. The main NT is ...
adrenergic receptor; Norepinephrine
Some other Adrenergic NT are..
acetylcholine(preganglion), Norepinephrine(post ganglion), epinephrine, dopamine
Alpha1 receptors ..., while Beta1 increases ... .., and Beta2 does...., and Dopaminergic1 ....
constrict; heart rate; bronchial dilation, uterine relaxation, vasodilation, liver glycogenolysis; dilates renal vessels
Parasympathetic system does the acronym sludge, which stands for..., and dumbels, which stands for...
salivation,lacrimation(secretion of tears),urinary incontinence,diarrhea,gastrointestinal cramps, emesis(vomiting); diarrhea,urination,miosis(constriction of eyes),bronchospasms,emesis,lacrimation,saliva
Drugs that are similar ...while drugs that block...
Non-selective adrenergic agonist NT are.., which are needed in ... duration, cannot be given..., and do not cross the ... .. ....
catecholamines(epinephrine); short; orally;does not cross the blood brain barrier; elevated BP, HR, resp, angina, hemorrhage, arrhythmias, temors;
Selective adrenergic agonist NT are..., which are needed in ... duration, and can be given .., and do cross the .. .. ..
non catecholamines(ephedrine); longer; orally; blood brain barrier
Other selective adrenergic agonists NT are...
psuedoephedrine(sudafed), phenylephrine(neo-synephrine), amphetamine(dexadrene)=ADHD
Alpha antagonists can be used therapeutically and cause...
hypertention, vasospasm, prostatic outflow
A Beta adrenergic antagonist drug is ..
propranol (inderal); for hypertension, angina(heart pain), irregular heart rhythms, migrains, glaucoma; give po
Nursing implications with Beta antagonists are...
moniter HR and BP. Must not stop suddenly, postural hypotension, depression, and insomnia
Parasympathetic agonist drugs are...
1.bethanachol (urecholine): increase bladder tone, urinary excretion and GI secretions, induce miosis; causes hypertention, bronchospasms
2.Nicotine (nicotrol): used for smoking cessation; causes respiratory paralysis, bronchospasms, muscle twitching; have atropine around
Therapeutic indirect-acting Cholinergic agonists drugs are...
Tensilon for Myasthenia gravis(droopy eye)
Mestinon, neostigmine(prostigmin), eserine for glaucoma, aricept for alzheimers and dementia
What do cholinergic antagonists do? Some examples of use are...
block acetycholine receptors(muscurinic and nicotinic); for pre-op decrease secretions prior to anesthesia, restore cardiac rate and blood pressure after vagal stimulation, relieve bradycardia, treat parkinsonism, relax biliary and urethre colic, relax bladder and tighten sphincter, relax uterine
Some examples of cholinergic antagonists drugs are..
belladonna alkaloids(dilate eye)-Atropine(give in small doses, causes slight bradycardia through vagal stimulation, causes drowsiness, blurred vision, dry mouth, urinary retention, can make you mean[psychotic effect], very red[peripheral dilatation], blindness[mydraisis]; be precautious with elderly, glaucoma, renal, prostate enlargement
Alpha adrenergic Antagonists cause...Some therapuetic medications are...Some actions are...Some side effects are..Some nursing considerations are...
hypertention, vasospasms, protostatic outflow; Flomax(for prostatic hypertrophy), prazosin; decreases sympathetic tone, dilate arteries/veins, lowers BP; dizziness, headache, weakness; give before bedtime die to orthostatic hypotension, monitor vitals and edema
