Question

Name a drug that alters synaptic transmission in the following ways:

a. blocks the action of the neurotransmitter at the postsynaptic membrane

__________________.

b. blocks the reuptake of the neurotransmitter at the presynaptic membrane

________________.

c. blocks the release of the neurotransmitter ___________________ and

___________________.

Answer 1

"a"opiates bind to receptors in the brain and block transmission of pain; Demerol, codeine, and methadone act similarly (On post synaptic membrane)

"b"  Cocaine blocks the reentering of dopamine back into the presynaptic neuron, leaving these neurotransmitters in the synaptic gap longer.

"c" Botulinum toxin  blocks release of the neurotransmitter acetycholine .
