Physio ex 6; activity 4
the parasympathetic nervous system releases ____________ to affect heart rate -
ANSacetylcholine
a cholinergic drug that worked the same as acetylcholine would - ANSbe an agonist and
decrease heart rate
norepinephrine affects the heart by.... - ANSincreasing the rate of depolarization and increasing
the frequency of action potentials
the _____________ receptor binds norepinephrine and epinephrine - ANSB-1 adrenergic
pilocarpine is a cholinergic drug, an acetycholine agonist. Predict the effect that pilocarpine will
have on heart rate - ANSpilocarpine will decrease heart rate
atropine is another cholinergic drug, an acetycholine antagonist. predict the effect that atropine
will have on heart rate - ANSatropine will increase heart rate
what drug increases the heart rate and mimics the sympathetic nervous system? -
ANSepinephrine
the chemical modifier we will look at is digitalis. individuals with weakened hearts need to allow
maximum time for venous return and increased stroke volume and would therefore most likely
benefit from... - ANSincreased force of contraction and decreased heart rate
pilocarpine decreased the heart rate. typical of cholinergic agonists.. - ANSdecreased the
frequency of action potentials
the effect of atropine was to... - ANSmimic the sympathetic nervous system
the modifiers tested that decrease the heart rate were - ANSdigitalis and pilocarpine
to increase the heart rate, the best choices would be - ANSepinephrine and atropine
describe the effect that pilocarpine had on the heart and why it had this effect - ANSpilocarpine
caused the heart to decrease
