autonomic nervous system Flashcards
two parts of peripheral nervous system
autonomic nervous system
somatic nervous system
two parts of autonomic nervous system
sympathetic nervous system
parasympathetic nervous system
autonomic nervous system is also called
visceral nervous system
autonomic nervous system ennervates
smooth muscles and glands + involuntary functions
- heart (control/regulation)
- respiratory
- gi
- bladder
- eyes
- glands
sympathetic nervous system neurotransmitters
are catecholamines: epinephrine, norepinephrine, dopamine
parasympathetic nervous system neurotransmitters
acetylcholine (aka cholinergic)
sympathetic nervous system receptors and sites
A1, A2, B1, B2
heart, bronchioles, gi tract, bladder, eye muscle
parasympathetic nervous system receptors
nicotinic
muscarinic
inactivates cholinergic neurotransmitters
acetylcholinesterase inactivates acetylcholine
sympathomimetic
adrenergic agonist
sympatholytic
adrenergic blocker
parasympathomimetic
cholinergic
parasympatholytic
anticholinergic
adrenergic agonists have the same effect as
plus hr example
parasympatholytics aka anticholinergics
HR goes up
adrenergic blockers have the same effect as
plus hr example
parasympathomimetics aka cholinergic agonists
HR goes down
