Block 3: Drugs and the ANS Flashcards
Acetycholine always binds to a —- receptor.
Cholinergic.
Drugs that bind to adrenergic receptors on effectors and stimulate a fight/flight response are…
Adrenergic agonists and sympathomimetics.
Drugs that bind to adrenergic receptors on effectors and block a fight/flight response are…
Adrenergic antagonists and sympatholytics.
Drugs that bind to muscarinic receptors on effectors and stimulate a rest/digest response are…
Cholinergic/muscarinic agonists and parasympathomimetics.
Drugs that bind to muscarinic receptors on effectors and block a rest/digest response are…
Cholinergic/muscarinic antagonist and parasympatholytics.
What receptor is found in sympathetic effector tissue (smooth muscle of blood vessels, iris dilator muscle, GI and urinary tract)
A1 receptors.
What receptor is found in the axon terminal of presynaptic neurons?
A2 receptors.
What receptor is found in sympathetic effector tissue (heart, adipose tissue, GI tract renal arterioles).
B1 receptors.
What receptor is found in sympathetic effect tissue (smooth muscle of bronchioles and uterus, blood vessels supplying the heart, skeletal muscle, brain and liver)
B2 receptors.
Adrenaline, noradrenaline, ephedrine, and dopamine are…
non-selective a and B agonists.
Phenylephrine is a…
