Nervous System
Nervous System
The nickname for the sympathetic nervous system
What is "fight or flight"?
The nickname for the parasympathetic nervous system
What is "rest and digest"?
This neurotransmitter uses both nicotinic and muscarinic receptors
What is acetylcholine?
The preganglionic neurotransmitter used in both the sympathetic nervous system and parasymapathetic nervous system
What is acetylcholine?
Stimulation of the sympathetic nervous system influences the heart in these two main ways
What is increased heart rate and increased contractility?
The parasympathetic nervous system uses this type of postganglionic receptor
What is muscarinic?
The enzyme that breaks down acetylcholine in the synapse
What is acetylcholinesterase?
The adrenal medulla is responsible for the secretion of these two catecholamines
What are epinephrine and norepinephrine?
This gland does not have postganglionic sympathetic fibers
What is the adrenal medulla?
Muscarinic receptors of the parasympathetic nervous system are coupled to these two GPCR pathways
What are Gq and Gi?
Methacholine, a muscarinic receptor agonist, is used in the diagnosis procedure of this condition
What is asthma?
The catecholamine precursor to epinephrine and norepinephrine
What is dopamine?
The beta adrenergic receptors in the sympathetic nervous system are coupled to this GPCR pathway
What is Gs?
What is craniosacral?
This drug is naturally-occurring in nightshade, Jimson weed, and mandrake plants
What is atropine?
Norepinephrine has more effects on these receptors
What are alpha receptors?
What is the M3 receptor?
This receptor decreases heart rate and atrial contractility in the parasympathetic nervous system
What is the M2 receptor?
The chemical warfare agent sarin uses the same mechanism of action as this type of poisoning that is commonly seen in farmers
What are organophosphates/pesticides?
This neurotransmitter causes bronchodilation
What is epinephrine?
