Serotonin, norepinephrine, and dopamine are a group of neurotransmitters collect

Question

Serotonin, norepinephrine, and dopamine are a group of neurotransmitters collectively called monoamines. A lack of these monoamines has been linked to depression. Depression is treated with drugs that prolong the effect of these neurotransmitters either by preventing the re-uptake of the neurotransmitters, or by inhibiting the enzyme that breaks down these neurotransmitters. Which of the following statements about neurotransmitters are true? The table lists the classifications of three antidepressants. Check all that apply. MAO inhibitors are examples of monoamine antagonists. Depression may be treated with monoamine agonists. Fluoxetine inhibits the enzyme that breaks down monoamines. A deficiency of serotonin, norepinephrine, and dopamine is associated with depression. Amitriptyline and fluoxetine both prevent the re-uptake of serotonin and norepinephrine. Some drug addictions are the result of dopamine agonists. Dopamine plays a role in feelings of pleasure and pain.

Explanation / Answer

True- MOA inhibitors are examples of monamine antagonists.

True- Depression may be treated with monoamine agonists-

Monamine agonists can decrease the depression but monamine antagonist(Resperine) can induce depression.

False- Fluxetine inhibits the enzyme that breaks down monamines.

True- A deficiency of serotonin,norepinephrine and dopamine is associated with depression.

These are involved in mood and thought to be connected to the depression.

True- Amitriptyline and fluxetine both prevent the re-uptake of serotonin and norepinenephrine.

Amitriptyline and Fluxetine relieves neuropathic pain by blocking the reuptake of serotonin and norepinephrine.

True- some drug addictions are the result of dopamine agonists.

Cocaine and amphetamines inhibits the reuptake of of dopamine.Cocaine is dopamine transporter blocker that competitevely inhibits dopamine upatke to increse the presence of Dopamine.

True- Dopamine plays a role in feelings of pleasure and pain.

Dopomine is nuerotransmitter released by brain and plays a number of roles like movement memory pleasurable reward behavior and cognition attention inhibitionof prolactin production sleep mood learning.
