2. Wernicke's area is associated with which of the following functions?
A) Speech production
B) Speech comprehension
C) Motor coordination
D) Visual processing
Correct Answer: B
Rationale: Wernicke's area is responsible for speech comprehension. Damage to
this area results in receptive aphasia.
3. The limbic system is associated with which of the following functions?
A) Motor coordination and balance
B) Emotion and learning

C) Visual processing
D) Speech production
Correct Answer: B
Rationale: The limbic system is primarily associated with emotion, learning, and
memory formation.
4. Which brain structure is most associated with long-term memory?
A) Amygdala
B) Thalamus
C) Hippocampus
D) Hypothalamus
Correct Answer: C
Rationale: The hippocampus is critically involved in the formation and
consolidation of long-term memories.

5. The central sulcus separates which two lobes of the brain?
A) Temporal lobe from occipital lobe
B) Frontal lobe from parietal lobe
C) Parietal lobe from occipital lobe
D) Frontal lobe from temporal lobe
Correct Answer: B
Rationale: The central sulcus separates the frontal lobe from the parietal lobe.
6. Which lobe of the brain is associated with movement, intelligence, and
