MSN 671 COMPLETE EXAM QUESTIONS AND ANSWERS
TO HELP YOU PASS
Which of the following is primarily inactivated by presynaptic reuptake
transporters? ANSWER GABA and serotonin
ANSWER signal transduction without an agonist or inverse agonist attached to
the receptor is known as constitutive activity.
What effect does a partial agonist have on neurotransmission? ANSWER net
agonism occurs when neurotransmission is low, and net antagonism occurs
when neurotransmission is high.
Agonists trigger ligand-gated ion channels to: ANSWER
Only when a neurotransmitter is present may both positive and negative
allosteric modulations occur.
The sodium flow that occurs when voltage-sensitive sodium channels are open
and active is: B. Out of the neuron - ANSWER into the neuron A. Into the
neuron
Which of the following describes how excitation-secretion coupling regulates
neurotransmission? ANSWER voltage-sensitive voltage channels for sodium-
sensitive calcium channels
A 21-year-old man and his parents arrive with a recent schizo diagnosis. He has
a conservative and straightforward language processing style; he can
comprehend and relate to basic inquiries, but he appears to lose his train of
thought when the conversation picks up speed. What pattern of cognitive
performance before psychosis would you most likely find when looking over
the patient's history? ANSWER premorbidly had cognitive impairment, and
during the prodromal phase, this decrease continued.
D1-like (D1 and D5 receptors) and D2-like (D2, D3, and D4 receptors) are two
types of DA receptors. What makes the two receptor groups different?
