1. Which structure connects the two cerebral hemispheres?
A. Internal capsule
B. Corpus callosum
C. Thalamus
D. Fornix
Answer: B. Corpus callosum
The corpus callosum is the major commissural fiber bundle
connecting the left and right cerebral hemispheres.
2. The primary motor cortex is located in which gyrus?
A. Postcentral gyrus
B. Precentral gyrus
C. Superior temporal gyrus
D. Cingulate gyrus
Answer: B. Precentral gyrus
The precentral gyrus contains the primary motor cortex responsible
for voluntary motor activity.
3. Which cranial nerve controls lateral eye movement?
A. CN III
B. CN IV
C. CN VI
D. CN II
,Answer: C. CN VI
The abducens nerve (CN VI) innervates the lateral rectus muscle,
allowing lateral eye movement.
4. The thalamus primarily functions as:
A. Motor planning center
B. Sensory relay station
C. Memory storage site
D. Hormone secretion center
Answer: B. Sensory relay station
The thalamus relays sensory information (except olfaction) to the
cerebral cortex.
5. Damage to the hippocampus most affects:
A. Vision
B. Hearing
C. Memory formation
D. Motor coordination
Answer: C. Memory formation
The hippocampus plays a key role in converting short-term memory
into long-term memory.
6. Which lobe is responsible for visual processing?
A. Frontal lobe
B. Temporal lobe
C. Occipital lobe
D. Parietal lobe
,Answer: C. Occipital lobe
The occipital lobe houses the primary visual cortex.
7. The cerebellum primarily regulates:
A. Emotion
B. Coordination
C. Vision
D. Smell
Answer: B. Coordination
The cerebellum coordinates voluntary movements and balance.
8. Which structure contains cerebrospinal fluid (CSF)?
A. Basal ganglia
B. Ventricles
C. Corpus callosum
D. Pons
Answer: B. Ventricles
The ventricular system contains CSF, which cushions and supports the
brain.
9. The blood-brain barrier is primarily formed by:
A. Astrocytes
B. Microglia
C. Oligodendrocytes
D. Schwann cells
Answer: A. Astrocytes
Astrocyte foot processes contribute to the formation of the blood-
brain barrier.
, 10. Which structure connects the brain to the spinal cord?
A. Cerebellum
B. Brainstem
C. Hypothalamus
D. Basal ganglia
Answer: B. Brainstem
The brainstem includes the midbrain, pons, and medulla and
connects the brain to the spinal cord.
11. The medulla oblongata regulates:
A. Memory
B. Emotion
C. Vital autonomic functions
D. Speech
Answer: C. Vital autonomic functions
The medulla controls breathing, heart rate, and blood pressure.
12. Which cranial nerve is responsible for smell?
A. CN I
B. CN II
C. CN III
D. CN V
Answer: A. CN I
The olfactory nerve (CN I) carries sensory information related to
smell.
13. The internal capsule contains:
