Autonomic Nervous System A and P Flashcards
General function of sympathetic nervous system?
Catabolic, energy expending, “fight or flight”
General functions of the parasympathetic nervous system?
Anabolic, conserve energy, “rest and digest”
Sympathetic nervous system uses what neurotransmitter and what receptor at the preganglionic to postganglionic junction?
Acetylcholine on a nicotinic receptor
Parasympathetic nervous system uses what neurotransmitter and what receptor at the preganglionic to postganglionic junction?
Acetylcholine on a nicotinic receptor
Sympathetic nervous system uses what neurotransmitter and what receptor at the postganglionic to target junction?
Norepinephrine on an adrenergic receptor
Parasympathetic nervous system uses what neurotransmitter and what receptor at the postganglionic to target junction?
Acetylcholine on a muscarinic receptor
T/F? Parasympathetic nervous system uses only acetylcholine?
True
What types of receptors does the parasympathetic nervous system use?
Nicotinic on postganglionic nerve
Muscarinic on target
What type of neurotransmitter does the sympathetic nervous system use?
Acetylcholine and norepinephrine
What type of receptors does the sympathetic nervous system use?
Nicotinic and adrenergic
Most impulses of the sympathetic nervous system are due to release of?
Catecholamines- Epinephrine and norepinephrine
What are the types of adrenergic receptors?
alpha 1, alpha 2, beta 1, beta 2
Norepinephrine works on what type of adrenergic receptors?
alpha 1, alpha 2, beta 1
Epinephrine works on what type of adrenergic receptors?
alpha 1, alpha 2, beta 1, beta 2
What are the functions of the parasympathetic nervous system?
BB SLUDGE Bradycardia Bronchospasm Salivation Lacrimation Urination Defecation GI motility Eye - contraction/constriction
