ANS - Parasympathetic - Term for postganglionic fiber
Cholinergic (4) =
1. preganglionic (parasympathetic)
2. postganglionic (parasympathetic)

ANS - Sympathetic - Enzymes to terminate action
COMT = Catechol-O-Methyl transferase
MAO = Monoamine oxidase
ANS - Parasympathetic - Enzymes to terminate action
Acetylcholinesterase
ANS - Sympathetic - Receptors (Need to know these)
1. only on target
2. found in different targets
Alpha, Beta 1, Beta 2
ANS - Parasympathetic - Receptors
Nicotonic (on ganglion), Muscarinic (on target) = named for the poisons that block them
ANS - Sympathetic - Nickname
Fight or flight
ANS - Parasympathetic - Nickname
Rest & restore
or
rest & digest
ANS - Sympathetic - Effects (point & shoot)
are opposite
mostly stimulatory except for digestion
ANS - Parasympathetic - Effects (point & shoot)
are opposite
mostly inhibitory except:
1. digestion - stimulates
2. reproduction - stimulates
ANS - Sympathetic - Receptors
Alpha
in blood vessels - get vasoconstrictions (shrinking).
Ex. nasal decongestion can't use if high blood pressure)
ANS - Sympathetic - Receptors
Beta 1
in heart muscle - cause increase of force & rate of contractions
ex. beta blockers
ANS - Sympathetic - Receptors
Beta 2
in airways of lungs - open up airways
