Question 1

Hemicholinium

Answer 1

• cholinergic

- inhibits synthesis of Ach by inhibiting reentry of acetate into presynaptic membrane

Question 2

Vesamicol

Answer 2

• cholinergic

- inhibits Ach uptake and storage in the vesicle causing less ACh release with action potential

Question 3

Black widow spider venom

Answer 3

• cholinergic

- stimulates the release of ACh into the synaptic cleft

Question 4

Metyrosine

Answer 4

• adrenergic

- inhibits the synthesis of NE within the presynaptic membrane

Question 5

Bretylium

Answer 5

• adrenergic

- inhibits the release of NE into the synaptic cleft

Question 6

Amphetamine

Answer 6

• adrenergic

- stimulates the release of NE into the synaptic cleft

Question 7

Cocaine

Answer 7

• adrenergic

- inhibits the reuptake of NE back into presynaptic terminal so more NE remains in the synaptic cleft
