MSN 671 study guide
Presynaptic reuptake transporters are a major method of inactivation of which of the
following - answer serotonin and GABA
What is constitutive activity - answer signal transduction when no agonist or inverse
agonist is bound to the receptor
a partial agonist has what effect on neurotransmission - answer net agonism when
neurotransmission is deficient and net antagonism when neurotransmission is
excessive
Agonists cause ligand-gated ion channels to: - answer
positive and negative allosteric modulations - answer both are only possible in the
presence of a neurotransmitter
When voltage-sensitive sodium channels are open and activated, the flow of sodium is:
A. Into the neuron B. Out of the neuron - answerinto the neuron
which of the following are involved in regulating neurotransmission via excitation-
secretion coupling? - answervoltage-sensitive sodium channels
voltage-sensitive calcium channels
A 21-year-old man who has just been diagnosed with schizo presents with his parents.
He speaks with a reserved and simple language processing style; he is able to
understand and relate to simple questions but seems to get lost when the pace of convo
increases. when reviewing the patient's history, what pattern of cognitive functioning
prior to psychosis would you be most likely to find? - answerimpaired cognitive
functioning premorbidly with further decline during the prodromal phase
DA receptors can be categorized as D1-like (D1 and D5 receptors) and D2-like (D2, D3,
and D4 receptors). What differentiates the two group of receptors. - answerD1-like
receptors are excitatory and D2-like receptors are inhibitory
Symptoms of schizophrenia are hypothetically attributable to malfunctioning in the -
answermesocortical and mesolimbic pathways
for which set of disorder is psychosis considered an associated feature rather than a
defining feature for diagnosis? - answerBipolar mania, Parkinson's disease
The activation of N-methyl-d-aspartate (NMDA) receptors requires the presence of:
A. Glutamate only
