ANS Drugs

Question 1

Ach

Answer 1

preganglionic sympathetic (both for sweatglands, and somatic neuromuscular end plates); all for parasympathetic

Question 2

Amphetamine

Answer 2

sympathomimetic; facilitates the release of epi, norepi, and dopamine from adrenergic nerves

Question 3

Botulinum

Answer 3

blocks release of ACh from cholinergic nerves

Question 4

Cocaine

Answer 4

sympathomimetic; impairs reuptake of norepi and dopamine by adrenergic nerve endings; local anesthetic

Question 5

Dopamine

Answer 5

renal vasodilation, cardiac stiumlation

Question 6

Hemicholiniums

Answer 6

inhibit transport of choline into cholinergeic nerves

Question 7

Hexamethonium

Answer 7

blocks all ANS ganglia and prevents autonommic compensatory reflexes

Question 8

Metyrosine

Answer 8

inhibits tryosine hydroxylase (inhibits norepi synthesis)

Question 9

Resperine

Answer 9

inhibits VMAT (transporter of dopamine and norepi into transmitter vesicles)

Question 10

Tetrodotoxin

Answer 10

blocks sodium channels (limits transmission in all nerves)

Question 11

Saxitoxin

Answer 11

blocks sodium channels (limits transmission in all nerves)

Question 12

Vesamicol

Answer 12

inhibits VAT (transporter of ACh into ransmitter vesicles)
