ANS Receptors Flashcards
Skeletal muscle contraction
NM - ligand gated Na K ion channel
Neuronal development and learning
NN - voltage gated Na K ion channel
Postganglionic neuron activation
NN - ligand gated Na K ion channel
Chromaffin cells releasing catecholamines to the blood
NN - ligand gated Na K ion channel
Higher cognitive function in brain neurons
M1 - Gq
Stimulates enteric nervous system
M1 - Gq
Inhibition of acetylcholine release from presynaptic terminal
M2 - Gi
Decrease in HR and contractility of atria
M2 - Gi
Increase lacrimal, sweat, salivary and gastric acid
M3 - Gq
Increase in insulin release
M3 - Gq
Increase in gut peristalsis
M3-Gq
Increase in bladder contraction
M3 - Gq
Pupillary constriction and accommodation
M3 - Gq
Bronchial constriction
M3 -Gq
Endothelium NO-mediated vasodilation
Think BP case
M3 - Gq
VASCULAR smooth muscle contraction
Alpha 1 - Gq
Pupillary dilation and aqueous humor production
Alpha 1 - Gq
Beta 1 & 2 - Gs
Intestinal and bladder constriction
Alpha 1 - Gq
Decreased norepinephrine release
Alpha 2 - Gi
Decrease in insulin release
Alpha 2 - Gi
Increase in HR and contractility
Beta 1 - Gs
Increase in renin release
Beta 1 - Gs
Increase in lipolysis (adipocyte)
Beta 1 - Gs
Bronchial dilation
Beta 2 - Gs
Vasodilation of vessels in SKELETAL muscle
Beta 2 - Gs
Decrease in uterine tone
Beta 2 - Gs
Thermogenesis and increase in lipolysis (brown adipose tissue)
Beta 3 - Gs
