What could happen if a neurotransmitter level was too low or too high? Give an example.

Drugs called selective serotonin reuptake inhibitors (SSRIs) affect the reuptake of neurotransmitter by presynaptic cells. SSRIs are used for the treatment of depression.  Serotonin normally causes an excitatory postsynaptic potential. Explain why neurotransmitter reuptake is important.  And describe what effect the SSRI would have on the response of these postsynaptic cells and why.

True or False: Neurotransmitters have different shapes.

Multiple sclerosis (MS) is a condition in which neurons in the CNS become demyelinated. Why do you think a NCV (nerve conduction velocity) test is not useful in diagnosing MS?

Describe neurotransmitters. Be able to give an example.

Make a list of the different types of neurotransmitters used by the nervous system.  Include a description of each, including it’s chemical and functional classification.  Describe in general how each neurotransmitter is used by the body

Choose all of the processes below that are related to the nervous system communications: (multiple select question) A. Chemicals transported in blood B. Quick initiation and conclusion of regulatory effect in the body C. Slow initiation, but long-term regulatory effect in the body D. Chemicals released at synapses. E. Directly regulates the metabolism of tissues and cells

Fill in the blank:  An action potential is a rapid sequence of changes involving _______________________ and repolarization.

what different types of neurotransmitters are there and their functions?

Which of the following is NOT true regarding the changes that occur during an action potential. Check All That Apply When stimulus is sufficient to cause the threshold potential to be reached, the area stimulated opens its voltage-gated sodium channels.When stimulus is sufficient to cause the threshold potential to be reached, the area stimulated opens its voltage-gated sodium channels. After threshold is reached, the sodium ions move into the cell via the Na+/K+ pump, the inside of the cell becomes momentarily positive.After threshold is reached, the sodium ions move into the cell via the Na+/K+ pump, the inside of the cell becomes momentarily positive. At almost the same time as Na+ channels are closing, voltage-gated potassium channels open, allowing an increased movement of potassium ions out of the cellAt almost the same time as Na+ channels are closing, voltage-gated potassium channels open, allowing an increased movement of potassium ions out of the cell The…
