Autonomic Nervous System: Flashcards
Both PNS and ANS work on the same organs but have what effect?
opposite
Where do PNS come from
cranial and sacral
SNS comes from t
thoraccic and lumbar
what is ionatropic
ion channel see in the PNS
What is metabotropic
g coupled protien seen in both PSN and SNS
WHat is cholenerigc?
PNS and it broken down into nicotinic (ionotropic) and muscariniic (metabo tropic)
What is adrenergic?
the SNS and it metabotropic
epi and NE
All are nicotiinic where?
at the synaose
But at organ waht is adrenogenic
the SNS
at the organ, what is muscarinic?
PSNS
WHat muscarinic works on the heart?
M2
What is controlled by M3
SLUDS - salviation, lachrymation, urination, defecation, sweating
BAM - bronchoconstriction, abdominal cramps and miosis
DOn’t use muscarinic AKA PSNS on what?
peptic ulcers== would increase gastric acid
Ashtma/ COPD= bronchoconstriciton
CHF=- decreased cardiac output
Muscarinic can be used in insecticides what is reversal agent?
pralidoxime
What is the neurotransmitter with the SNS
adrengerigc = EPI AND NE
what adrenerigc receptor works witht he heart?
beta 1
alpha one does what
vasoconstricts, urinary retenttion, and pupil dialtion
what does alpha 2 do?
vasoconstircts
What does Beta 1 do?
tachycardia - rate, electical pulse, and contraciton strength
Beta 2 does what
bronchodialtion and vasodialation stops peristalsis
What activates all alpha and beta receoptors
EPI
What is epi reversal
vasocrstiction effect where the alpha blocker cancels the epi’s alpha effects adn only activates the beta receptors
what is the vasovagal refelx?
NE activates the barorecptors which reduces heart rate and leading to opposite of what NE typically does
