MSN 671 LATEST QUESTIONS AND ACCURATE ANSWERS
FOR GUARANTEED RESULTS
All human CNS neurons communicate with one another at synapses using the
following protocol: ANSWER Chemical
What is the term for neurotransmission that takes place without a synapse?
ANSWER Neurotransmission Volume
What is an instance of a neurotransmitter that is made exclusively in a
retrograde manner? ANSWER Oxygen nitrate
Which of the following best describes a volume neurotransmission? ANSWER
The prefrontal cortex's dopamine
Where is the second messenger produced in a signal transduction cascade
related to a G protein? ANSWER inside the cell
What kind of pump provides the energy needed to move monoamines? The
sodium pump is the answer.
What is the impact of a partial agonist on neurotransmission? ANSWER When
neurotransmission is low, there is net agonism; when neurotransmission is high,
there is net antagonistic effects.
When it comes to inverse agonists, which is true? ANSWER They are believed
to reduce signal transduction by stabilizing the G-protein-linked receptor in an
inactive state by a conformational shift.
Of the following, which one prevents all agonist spectrum actions? The
antagonists of the answer
What controls ligand-gated ion channel opening? Neurotransmitters with
answers
What controls voltage-gated ion channel opening? ANSWER The voltage
across the membrane
, When a neurotransmitter and a positive allosteric modulator bind to the same
receptor, what happens to the ion channel? ANSWER More ions can enter the
cell because the channel opens considerably more frequently.
How do ligand-gated ion channels react to agonists? ANSWER They increase
the frequency of ligand-gated ion channel openings.
ANSWER Both inside and outside the channel are the known receptor locations
for ligand-gated ion channels.
The sodium flow that occurs when voltage-sensitive sodium channels are open
and active is: ANSWER In the neuron
ANSWER Glutamate and glycine are necessary for the activation of N-methyl-
d-aspartate (NMDA) receptors.
ANSWER Hypo-functioning of NMDA receptors is one of the main theories of
psychosis.
It is thought that excessive glutamate release into the ventral trigeminal region
results from dysfunction at synapses that include NMDA receptors. What
effects on dopamine (DA) is this thought to have downstream? ANSWER DA
release that is too high in the NA and too low in the PFC
The notion that abnormal competitive elimination takes place is central to the
neurodevelopmental theory of schizophrenia. A phase of neurodevelopment
known as competitive elimination occurs when: ANSWER While regularly
utilized synapses are kept, seldom used synapses are pruned.
Which group of illnesses considers psychosis to be an associated feature rather
than a diagnostic defining feature? ANSWER Parkinson's disease with bipolar
disorder
Schizophrenia symptoms are supposedly caused by malfunctions in the
ANSWER The mesolimbic and mesocortical pathways
D1-like (D1 and D5 receptors) and D2-like (D2, D3, and D4 receptors) are two
types of dopamine (DA) receptors. What distinguishes the two receptor groups?
ANSWER Excitatory D1-like receptors and inhibitory D2-like receptors
