what receptor causes inc HR and increased force of contraction in the heart
B1
overstimulation of nicotinic muscular receptors can lead to what
paralysis
what are the 7 targets of B2 receptors
lungs
uterus
bladder
BV (skeletal, coronary)
liver
GI tract
skeletal muscles
what receptors causes inhibition of NE release from the presynaptic neurons
a2
what receptor causes lipolysis
B3
stimulation of M3 receptors does what
stimulates parasympathetic effects
diaphoresis (sympathetic NS)
what receptor is a part of the negative feedback loop and is found in the presynaptic neurons
a2
what receptor causes relaxation of the Bladder
B2 and B3
what receptor causes thick viscous secretions from the salivary glands
a1
what receptor causes contraction of the erector pili muscles
a1
where would you see muscarinic cholinergic receptors
on various organs acted on by the parasympathetic NS
on sweat glands acted on by the sympathetic NS
Name the 2 targets of B3 receptors
Adipose tissue
bladder
stimulation of nicotinic muscular receptors causes what
skeletal muscle depolarization and contraction
what receptors causes increased BP due to renin release from the kidneys
B1
where are M2 receptors
heart muscle
what receptor causes decreased GI secretions
a2
stimulation of nicotinic neuronal receptors in the ganglia causes what
kinda hard to predict since it stimulates both the sympathetic and parasympathetic systems
what receptor causes increased uptake of potassium in skeletal muscles
B2
name the 3 targets of the a2 receptors
presynaptic neurons
pancreas
GI tract
stimulation of nicotinic neuronal receptors in the adrenal glands causes what
epi and norepi to be released into the blood stream
what receptor causes vasoconstriction of skin and splanchnic blood vessels
a1
where are M1, M4, and M5 receptors
brain

a2
name the 6 targets of a1 receptors
blood vessels (skin, splanchnic)
internal urinary sphincter
