Affects of Drugs on Synapses (NERVES)

?
What are 4 examples of Chemicals that affect synapses?
Nicotine, Botox (Botulinum Toxin), Organophosphorous Insecticides and Beta Blockers
1 of 5
What is Nicotine's affect on synapses and how?
Nicotine has the same shape as Acetylcholine (neurotransmitter) so attaches to Postsynaptic receptors. This initiates action potentials and isn't broken down
2 of 5
What is Botox's affect on synapses and how?
Stops the release of Acetylcholine (neurotransmitter) at presynaptic synapses (found in bacteria in canned food)
3 of 5
What is Organophosphorous Insecticide's affect on synapses and how?
Inhibits Acetylcholinerase (breakdown of neurotransmitters) so continuous action potentials occur, causes illness/death from continuous reactions
4 of 5
What affect do Beta Blockers have on synapses and how?
Beta Blockers receptors for neurotransmitters (noradrenaline and adrenaline) reducing blood pressure as adrenaline doesn't inrease heart rate
