Autonomic Nervous System Drugs

The Autonomic Nervous System is divided into the __________ and the __________.

“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.

Cholinergic drugs are called __________ drugs because they stimulate __________ action.

Cholinergic drugs work at __________ receptors.

The transmitter affected by cholinergic drugs is __________.

__________ mimic the action of acetylcholine; whereas __________ inhibit acetylcholine destruction at receptor sites.

Because cholinergic agonists bind Parasympathetic Nervous System receptors, they can produce adverse effects in virtually any organ innervated by parasympathetic nerves.

Toxic insecticides and nerve gases are made of __________.

Which of the following are antidotes for cholinergic and anti-cholinesterase drugs?

Atropine __________.

Adrenergic drugs are called __________ drugs because they stimulate __________ action.

The transmitter(s) affected by adrenergic drugs is (are) __________.

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.

Direct-acting adrenergics __________; whereas indirect-acting adrenergics __________.

Adrenergic blocking drugs are called __________ drugs because they block __________ impulses.

Alpha blocker receptors are located on blood vessel walls where they cause vessel dilation when occupied.

Beta 1 receptors are primarily located in the __________; whereas beta 2 receptors are primarily located in the __________.
