Unit 2: Chapter 4: Drugs That Affect The Autonomic Activity

Question 1

Drugs that argument the parasympathetic nervous system: Ganglion stimulants

Answer 1

Nicotine drugs
1. Nicotine drugs in small doses: stimulate postganglionic neurons.
2. Anticholine esterase enzyme:
- Prostigmine.
- Di-isopropyl flourophosphate (DFp) (war poison).

Question 2

What do ganglion stimulants stimulate?

Answer 2

Both sympathetic and parasympathetic ganglia.

Question 3

Drugs that argument the parasympathetic nervous system: parasympathomimetic drugs

Answer 3

Stimulate Muscaranic receptors
1. Muscarine.
2. Pilocarpine.
3. Anticholine esterase drugs:
- Prostigmine.
- Di-isopropyl fluorophosphate (war poison).

Question 4

Drugs that depress the parasympathetic activity: ganglion blockers

Answer 4

1. Large doses of nicotine.
2. Tetraethyl ammonium.

Question 5

Drugs that depress the parasympathetic activity: parasympatholytic drugs

Answer 5

Block muscarine receptors
1. Atropine.

Question 6

Drugs that augment the sympathetic activity: ganglion stimulants

Answer 6

Nicotine drugs
1. Nicotine drugs in small doses: stimulate postganglionic neurons.
2. Anticholine esterase enzyme:
- Prostigmine.
- Di-isopropyl flourophosphate (DFp) (war poison).

Question 7

Drugs that augment the sympathetic activity: sympathomimetic drugs

Answer 7

1. Drugs that stimulate the a-adrenergic receptors: phenylephrine.
2. Drugs that stimulate the B-adrenergic receptors: isoprenaline.

Question 8

Drugs that depress the sympathetic activity: ganglion blockers

Answer 8

1. Large doses of nicotine.
2. Tetraethyl ammonium.

Question 9

Drugs that depress the sympathetic activity: sympatholytic drugs

Answer 9

1. Block a receptors: phentolamine.
2. Block B receptors: propranolol.
