SECTION 1: NEUROBIOLOGY AND NEUROTRANSMITTERS
QUESTION 1
Where is norepinephrine primarily produced in the brain?
A. Raphe nuclei
B. Substantia nigra
C. Locus coeruleus
D. Basal nucleus of Meynert
Answer: C. Locus coeruleus
Rationale: Norepinephrine is primarily synthesized in the locus
coeruleus located in the pons. It projects throughout the CNS and is
associated with arousal, attention, and stress response. Serotonin is
produced in the raphe nuclei, dopamine in the substantia nigra and
ventral tegmental area, and acetylcholine in the basal forebrain. This
is a high-yield board exam topic.
,QUESTION 2
The amygdala is primarily responsible for:
A. Memory formation
B. Emotional processing and fear responses
C. Executive function
D. Language comprehension
Answer: B. Emotional processing and fear responses
Rationale: The amygdala, a limbic structure, is central to processing
emotions, particularly fear and anxiety. It evaluates the emotional
significance of stimuli and generates appropriate behavioral
responses. It is hyperactive in anxiety disorders and PTSD. The
hippocampus is involved in memory; the prefrontal cortex in
executive function.
QUESTION 3
Dopamine pathways involved in schizophrenia include all of the following
EXCEPT:
A. Mesolimbic (positive symptoms)
B. Mesocortical (negative/cognitive symptoms)
C. Nigrostriatal (EPS)
D. Raphe-striatal
Answer: D. Raphe-striatal
Rationale: The raphe nuclei are the primary source of serotonin, not
dopamine. The main dopamine pathways are: mesolimbic (VTA to
nucleus accumbens, reward, positive symptoms), mesocortical (VTA to
prefrontal cortex, cognition, negative symptoms), nigrostriatal
,(substantia nigra to striatum, motor control, EPS), and
tuberoinfundibular (hypothalamus to pituitary, prolactin regulation).
QUESTION 4
GABA is the primary __________ neurotransmitter in the brain.
A. Excitatory
B. Inhibitory
C. Modulatory
D. Neurotrophic
Answer: B. Inhibitory
Rationale: GABA (gamma-aminobutyric acid) is the most abundant
inhibitory neurotransmitter in the CNS. It reduces neuronal
excitability and is the target of benzodiazepines and barbiturates,
which enhance GABA's effects to produce sedation, anxiolysis, and
anticonvulsant effects. Low GABA activity is associated with anxiety
disorders, insomnia, and seizures.
QUESTION 5
Glutamate is the primary __________ neurotransmitter in the brain.
A. Excitatory
B. Inhibitory
C. Modulatory
D. Neurotrophic
Answer: A. Excitatory
Rationale: Glutamate is the most abundant excitatory
neurotransmitter in the CNS. It is involved in synaptic plasticity,
learning, memory, and neural development. Excessive glutamate
activity can cause excitotoxicity, implicated in neurodegenerative
, disorders and stroke. NMDA receptor antagonists (e.g., ketamine)
have rapid antidepressant effects by modulating glutamate.
QUESTION 6
Which cytochrome P450 enzyme is induced by tobacco smoke and
metabolizes clozapine and olanzapine?
A. CYP2D6
B. CYP3A4
C. CYP1A2
D. CYP2C19
Answer: C. CYP1A2
Rationale: CYP1A2 is induced by polycyclic aromatic hydrocarbons in
cigarette smoke. It is the primary enzyme for clozapine and
olanzapine metabolism. Smokers require higher doses of these
medications. Fluvoxamine, ciprofloxacin, and caffeine inhibit CYP1A2.
This is a classic high-yield board question.
QUESTION 7
The mnemonic "CRAP GPS" represents drugs that are:
A. CYP inhibitors
B. CYP inducers
C. Highly protein-bound
D. Narrow therapeutic index
Answer: B. CYP inducers
Rationale: "CRAP GPS" is a mnemonic for CYP
inducers: Carbamazepine, Rifampin, Alcohol
(chronic), Phenytoin, Griseofulvin, Phenobarbital, St. John's Wort.
Inducers increase metabolism, decreasing serum levels of substrate
