1. A patient recovering from a stroke has trouble with speech
comprehension and works with a speech therapist twice a week. Which
part of the brain has been affected?
A) Broca's area
B) Basal ganglia
C) Limbic system
D) Wernicke's area
Correct Answer: D
Rationale: Wernicke's area, located in the superior temporal gyrus, is
responsible for language comprehension. Damage results in receptive
aphasia (Wernicke's aphasia), characterized by fluent but meaningless
speech and difficulty understanding language . Broca's area (frontal lobe)
is responsible for speech production.
, 2. Damage to the anterior portion of which lobe may cause astereognosis
(loss of ability to recognize objects via touch)?
A) Frontal lobe
B) Temporal lobe
C) Parietal lobe
D) Occipital lobe
Correct Answer: C
Rationale: The parietal lobe processes somatosensory information,
including touch, pressure, temperature, and pain. Damage to the anterior
parietal lobe (postcentral gyrus) disrupts the primary somatosensory
cortex, resulting in the inability to recognize objects through tactile
manipulation despite intact sensory pathways .
3. The limbic system is primarily associated with which functions?
A) Motor control and coordination
,
B) Emotion and learning
C) Visual processing
D) Language production
Correct Answer: B
Rationale: The limbic system includes structures such as the hippocampus,
amygdala, hypothalamus, and cingulate gyrus. It plays a central role in
emotional processing, memory formation, motivation, and the regulation
of autonomic and endocrine responses . The amygdala processes
emotional significance and fear responses, while the hippocampus
consolidates memories.
4. Which brain structure is most associated with long-term memory
formation?
A) Amygdala
B) Hypothalamus
C) Hippocampus
,
D) Thalamus
Correct Answer: C
Rationale: The hippocampus is essential for the consolidation of short-
term memory into long-term memory. Damage to the hippocampus
results in anterograde amnesia (inability to form new memories) . The
amygdala is involved in emotional memory; the hypothalamus regulates
autonomic functions.
5. Which brain structure is involved in voluntary motor movements?
A) Basal ganglia
B) Prefrontal cortex
C) Amygdala
D) Limbic system
Correct Answer: A
Rationale: The basal ganglia (caudate, putamen, globus pallidus,
substantia nigra) initiate and modulate voluntary movement via cortico-
