para vs sympathetic

QuestionAnswer
Heart Parasympathetic Effect-decreases rate and contractile force Sympathetic effect- increases rate and contractile force.
Lungs Parasympathetic effect- Bronchoconstricts Sympathetic effect- Bronchodilates
Eyes Parasympathetic effects-Pupil constriction Sympathetic effects-Pupil dilation
Hair muscles Parasympathetic effects-Relaxes Sympathetic effects -contracts and causes hair to stand on end (piloerection)
Gastrointestinal Parasympathetic effect- increases digestion sympathetic effect- decreases digestion
urinary Parasympathetic effect- Constricts bladder sympathetic effect- relaxes bladder
Adgernergic receptors
Alpha 1 Tissue-Vascular smooth muscle,pupil,pilomotor smooth muscle. Action- contracts, dilation (mydriasis), goose bumps.
Beta 1 Tissue- heart Action- stimulates rate and force
Beta 2 Tissue- Respiratory, somatic motor ( voluntary muscle) Action- Bronchodilates, tremors
Dopamine Tissue- Renal Action- Relaxes arteries
Cholinergic agonist and indications
Direct acting- stimulates cholinergic receptors Bethanechol indication- urinary retention
Direct acting-stimulates cholinergic receptors Succinylcholine indications- neuromuscular blockade- intubation
Direct acting-stimulates cholinergic receptors Pilocarpine indications-Glaucoma
indirect-acting-decreases AChE activity Neostigmine Myasthenia gravis
indirect-acting decreases AChE activity- Pyridostigmine Reversal of neuromuscular blockade
indirect-acting decreases AChE activity- Malathion Insecticide
indirect-acting decreases AChE activity-nerve gas Chemical Warfare
Anticholinergic drug class
catagory and function- antimuscarinics- increases heart rate and bronchodilation drug- Atropiine ipratropium brormide (atrovent)
Nicotinic blockers-at preganglionic sites- prevent nervous transmission drug- hexamethonium
Sympathomimetic drugs
Catecholamines- Epinephrine indications- anaphylaxis
catecholamines- norepinephrine indications - hypotension
catecholamines- dopamine indications- shock
catecholamines- dobutamine indications- shock, heart failure
phenylephrine indications- nasal decongestant. hypotension
albuterol indications- asthma
sympatholytic drug sub group
alpha-blocker- drug- Doxazosin indications- hypertension, benign prostate hypertrophy
Beta-blocker- drug- propranolol indication- hypertension
Cholinergic/Parasympathomimetic drugs that stimulate or mimic the parasympathetic receptors
Anticholinergic/ Parasympatholytics drugs that block parasympathetic receptors
Adrenergic/sympathomimetics drugs that stimulate or mimic the sympathetic receptors
Antiadrenergic/sympatholytics drugs that would antagonize the sympathetic response.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
