Answer 1

Central Nervous System (CNS)

Question 2

• Part of the PNS
• Controls body’s autonomic or involuntary functions

Answer 2

Autonomic Nervous System

Question 3

Process of chemical signalling between cells. Signal stored in nerve terminal, released from nerve ending, bound to a receptor

Answer 3

Neurochemical Transmission

Question 4

Neurotransmitter that initiates PNS responses

Answer 4

Acetylcholine

Question 5

• Drugs that mimic or inhibit neurotransmission
• Inhibits the release of neurotransmitters
• Block receptor sites

Answer 5

Altering Neurotransmission with Drugs

Question 6

Neurons and effector organs activated activated by acetylcholine

Answer 6

Cholinergic

Question 7

What doe Cholinergic drugs do to the PNS?

Answer 7

• Cholinergic drugs mimic PNS influence
• Anticholinergic drugs block PNS influence

Question 8

Neurons and effector organs activated by norepinephrine/epinephrine

Answer 8

Adrenergic

Question 9

What do Adrenergic Drugs do to the body?

Answer 9

• Adrenergic drugs cause adrenaline effects
• Anti-adrenergic drugs black the effects of adrenaline-like drugs

Question 10

Adrenergic Receptor Classifications

Answer 10

ALPHA-ADRENERGIC
- Alpha 1: receptor stimulation causes artery and venous constriction
- Alpha 2- receptor stimulation blocks
BETA-ADRENERGIC
- Beta 1: causes increased force and contractility of heart
- Beta 2: causes bronchodilation in the lungs

Question 11

Mimic sympathetic stimulation

Answer 11

Sympathomimetics

Question 12

Drug that binds to a receptor and causes it to initiate the expected response

Answer 12

Agonist

Question 13

Drug binds to a site but does not cause the expected response. Blocks another drug from triggering the same response

Answer 13

Antagonist

Question 14

Binds to a receptor and causes the expected response but blocks another drug from binding to that site

Answer 14

Agonist-Antagonist
