“Re-uptake” allows the neurotransmitter to be recycled into the nerve ending for the next transmission.
The __________ neuron releases neurotransmitter into the synaptic cleft; the __________ neuron contains receptors that, when filled, initiate a signal.
pre-synaptic; post-synaptic
post-synaptic; pre-synaptic
Cholinergic drugs are called __________ drugs because they stimulate __________ action.
para-sympathomimetic; parasympathetic
sympathomimetic; sympathetic
Cholinergic drugs work at __________ receptors.
a. alpha
b. beta
c. dopamine
d. muscarinic
e. nicotinic
f. two (2) of the above are correct
The transmitter affected by cholinergic drugs is __________.
acetylcholine
epinephrine
norepinephrine
dopamine
__________ mimic the action of acetylcholine; whereas __________ inhibit acetylcholine destruction at receptor sites.
Cholinergic agonists; anti-cholinesterases

Atropine
b. Belladonna
c. Hyoscyamine
d. all the above are correct
Atropine __________.
a. blocks cholinergic activity in the eye
b. causes mydriasis
c. causes the pupil to dilate
d. all the avove are correct
Adrenergic drugs are called __________ drugs because they stimulate __________ action.
The transmitter(s) affected by adrenergic drugs is (are) __________.
a. acetylcholine
b. epinephrine
c. norepinephrine
d. dopamine
e. b, c, and d are correct
Non-catecholamines cannot be taken orally because they are destroyed by digestive enzymes.
“Synthetic” catecholamines have a shorter duration of action than “natural” catecholamines produced by the body.
Positive chronotropic effects make the heart beat faster.

Beta 1 receptors are primarily located in the __________; whereas beta 2 receptors are primarily located in the __________.
heart; bronchi and blood vessels
bronchi and blood vessels; heart
heart; bladder
bladder; bronchi and blood vessels
