From the information provided, drugs used to treat Parkinson’s disease symptoms will act at which location? multiple choice 2 The globus pallidus The substantia nigra The striatum 3. Which of the following might be therapeutic in the treatment of Parkinson’s disease symptoms? multiple choice 3 all of these choices listed may be therapeutic increasing dopamine receptor responsiveness monoamine oxidase inhibition increasing dopamine release decreasing dopamine…where are the locations you can these neurotransmitters: Norepinephrine Epinephrine Serotonin Glutamate Gamma-aminobutyric acid (GABA) AcetylcholineSpastic paralysis (resulting from the failure of muscles to relax), induced by the neurotoxin strychnine, occurs when this poison blocks the binding of: the excitatory neurotransmitter acetylcholine to post-synaptic sodium channels the excitatory neurotransmitter glutamate to post-synaptic calcium channels the excitatory neurotransmitter serotonin to post-synaptic potassium channels the inhibitory neurotransmitter glycine to post-synaptic chloride channels the inhibitory neurotransmitter melatonin to post-synaptic bicarbonate channels
- Which of the following neurotransmitters serve as the body's natural painkiller? Acetylcholine Endorphins DopamineWhich of the following autonomic system neurotransmitters and receptors is/are correctly matched? Acetylcholine : beta adrenergic receptors Epinephrine : nicotinic cholinergic receptors All of these are correctly matched Norepinephrine : alpha adrenergic receptorsThe following diagram represents a typical serotonergic synapse. Where, specifically, do antidepressants work (e.g. SSRI)? Neurotransmitter Neurotransmitter transporter Аxon Synaptic vesicle terminal Voltage- gated Ca?+ channel Synaptic cleft Receptor Postsynaptic density Dendrite Neurotransmitter Synaptic Vesicle Neurotransmitter transporter (aka Reuptake transporter) Receptor O All of the above
- Flaccid paralysis (resulting from the failure of muscles to contract), induced by the neurotoxin tubocurarine, occurs when this poison blocks the binding of: the inhibitory neurotransmitter melatonin to post-synaptic bicarbonate channels the excitatory neurotransmitter glutamate to post-synaptic calcium channels the excitatory neurotransmitter acetylcholine to post-synaptic sodium channels the inhibitory neurotransmitter glycine to post-synaptic chloride channels the excitatory neurotransmitter serotonin to post-synaptic potassium channelsWhich second messenger system is used with beta-1 adrenergic receptors? cyclic AMP ATP calciumChlorpromazine and Bromocriptine both have the affinity in the dopamine receptors of the Central Nervous System, Chlorpromazine is use to treat schizophrenia and psychosis whereas Bromocriptine is use to treat parkinson’s disease. Explain the action of these drugs in the dopamine receptor and why they have different effects and clinical use, knowing that they both act on the dopamine receptors.
- The following compounds exhibit little to no adrenergic receptor function. Consider what components of adrenaline and noradrenaline are necessary for their action as agonists in light of this knowledge. Explain your response. Assume that the pH of the body is 7.Beta blockers are a class of drugs that inhibit the action of what neurotransmitter? O norepinephrine beta glucan dopamine acetylcholineWhich of the following is an effect of cocaine and amphetamine?
