where are the locations you can these neurotransmitters: Norepinephrine Epinephrine Serotonin Glutamate Gamma-aminobutyric acid (GABA) Acetylcholine

What is the role of oxidate stress in the development of Parkinson's disease? Oxidative stress plays an important role in the degeneration of dopaminergic neurons in Parkinson's disease. The disruptions in the physiologic maintenance of redox protection in neurons interfere with the process, which ends up leading to cell death?

which way does the neurotransmitter NO move

Draw a presynaptic and postsynaptic neuron at to demonstrate the release and acceptance of a neurotransmitter. Identify the following in your drawing: Ca2+, synaptic cleft, receptor, synaptic vessicle, SNARE, presynaptic neuron, postsynaptic neuron

Antidepressants work by O increasing presynaptic GABA secretion. increasing serotonin reuptake by the neuron. decreasing BDNF secretion by neurons. decreasing serotonin reuptake by the presynaptic terminal. All the answers are possible.

Choosing one neurotransmitter, discuss neurotransmission from synthesis to release in the presynaptic neuron to binding and generation of a postsynaptic potential in the postsynaptic neuron.

Correct answer: Ligand-gated ion channel don’t open until the neurotransmitter diffuses across the synapse and binds to the receptor, The calcium channels are blocked in the presynaptic cells, It takes time for the vesicular exocytosis to occur Please explain why each of the correct answer choices are correct. Thank you.

Parkinson's disease causes tremors and slow movement due to the brain's inability to produce enough dopamine. Thus, to treat Parkinson's, doctors would MOST likely prescribe a dopamine: efferent. agonist. antagonist.

Vitamins B1, B6 and B12 are so-called "Neurotropic" vitamins. They may response to "Wallerian degeneration" in nerve system. Briefly describe"Wallerian degeneration" and how the "neurotropic" vitamins react with this process.

Studies have shown that individuals with attention deficit hyperactivity disorder (ADHD) may have lower than normal amounts of dopamine and norepinephrine excitatory neurotransmitters in their synapses. Methylphenidate is one of the drugs prescribed to individuals with ADHD. It prevents the reuptake of dopamine and norepinephrine neurotransmitters from the synapses, thereby keeping these neurotransmitters in the synapses longer. Which of the following rows correctly identify the effects of methylphenidate in individuals with ADHD? Select one: a. There is an increase in the permeability of the presynaptic neuron to potassium ions. b. There is a increase in the permeability of the postsynaptic neuron to potassium ions. c. There is an increase in the permeability of the presynaptic neuron to sodium ions. d. There is a increase in the permeability of the postsynaptic neuron to sodium ions.
