Question 1
Which part of the brain is primarily responsible for executive functions such as
planning and decision-making?
A. Occipital lobe
B. Frontal lobe
C. Temporal lobe
D. Cerebellum
Correct Answer: B
Rationale:
The frontal lobe, particularly the prefrontal cortex, is responsible for executive
functions including planning, reasoning, judgment, and decision-making. The
occipital lobe processes vision, the temporal lobe is involved in hearing and
memory, and the cerebellum coordinates movement and balance.
Question 2
Which neurotransmitter is primarily associated with reward and motivation?
A. GABA
B. Dopamine
C. Acetylcholine
D. Glycine
Correct Answer: B
,Rationale:
Dopamine plays a central role in reward, motivation, reinforcement, and
movement. GABA is inhibitory, acetylcholine is involved in learning and muscle
activation, and glycine is another inhibitory neurotransmitter.
Question 3
Which neurotransmitter is the primary inhibitory neurotransmitter in the central
nervous system?
A. Dopamine
B. Serotonin
C. GABA
D. Norepinephrine
Correct Answer: C
Rationale:
Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in
the brain, reducing neuronal excitability.
Question 4
The hippocampus is primarily involved in:
A. Vision
B. Formation of new memories
C. Language production
D. Balance
Correct Answer: B
Rationale:
The hippocampus is essential for forming and consolidating new declarative
memories.
Question 5
,Which lobe primarily processes visual information?
A. Frontal
B. Temporal
C. Occipital
D. Parietal
Correct Answer: C
Rationale:
The occipital lobe contains the primary visual cortex and is responsible for
processing visual input.
Question 6
The amygdala is most closely associated with:
A. Emotional processing
B. Fine motor coordination
C. Speech production
D. Visual perception
Correct Answer: A
Rationale:
The amygdala plays a major role in processing emotions, particularly fear and
threat detection.
Question 7
Which nervous system controls voluntary skeletal muscle movement?
A. Autonomic nervous system
B. Sympathetic nervous system
C. Somatic nervous system
D. Parasympathetic nervous system
Correct Answer: C
, Rationale:
The somatic nervous system controls voluntary movement of skeletal muscles.
Question 8
The sympathetic nervous system is primarily responsible for:
A. Rest and digestion
B. Sleep regulation
C. Fight-or-flight responses
D. Memory consolidation
Correct Answer: C
Rationale:
The sympathetic nervous system prepares the body for stressful or emergency
situations.
Question 9
Which brain structure coordinates balance and voluntary movement?
A. Thalamus
B. Cerebellum
C. Hypothalamus
D. Medulla
Correct Answer: B
Rationale:
The cerebellum coordinates balance, posture, and precise motor movements.
Question 10
Which brain structure regulates body temperature and hunger?
A. Hippocampus
B. Hypothalamus
