ANS agents

QuestionAnswer
Dilates pupils sympathetic response
Dialates bronchioles sympathetic response
Increases heart rate sympathetic response
constricts blood vessels sympathetic response
relaxes smooth muscles of gi tract sympathetic response
relaxes bladder muscle sympathetic response
relaxes uterine muscle sympathetic response
constricts pupils parasympathetic response
constricts bronchioles and increases secretion parasympathetic response
decreases heart rate parasympathetic response
dialates blood vessels parasympathetic response
increases peristalsis parasympathetic response
constricts bladder parasympathetic response
increases salivation parasympathetic response
The parasympathetic nervous system is called the _________ Cholinergic system
NT associated with the parasympathetic nervous system acetylcholine
Cholinergic receptors muscarinic and nicotinic
The sympathetic nervous system is called the _______ adrenergic system
NTs associated with the adrenergic system epinephrine and norepinephrine
Adrenergic receptors alpha1, alpha2, beta1, beta2
Alpha 1 receptor effects vasoconstriction, increased bp, positive inotrope, mydriasis, bladder contraction, prostate contraction.
Alpha 2 recpetor effects reduced norepinephrine= decreased bp, decreased gi tone and motility
Beta 1 receptor effects positive chromotropic, positive inotrophic, positive dromotrophic, increased renin secretion = increased bp
Beta 2 receptor effects decreased gi tone and motility, bronchodilation, relaxation of uterine muscle, gylocogenolysis=increase glucose lvl
dopaminergic receptor effects renal, mesenteric, coronary, cerebral arties dilate = increased blood flow.
Transmitters are inactivated by reuptake into the neuron, transformation by enzyme, diffusion
Enzymes that inactivate norepinephrine MAO (inside neuron) COMT (outside neuron)
Epinephrine subq dosing 0.1-0.5ml of 1:1000
Epinephrine iv dosing 0.1-0.25mg of 1:10000
Epinephrine considerations needs cardiac ecg monitoring.....dysrrhymias

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:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
