Questions 1–70+
SECTION 1: NEUROANATOMY & BRAIN STRUCTURES (Questions 1–30)
1. A 65-year-old patient suffers a stroke that damages the posterior region
of their brain. Which deficit is most likely to result?
A) Inability to understand spoken language
B) Loss of vision
C) Paralysis of the left arm
D) Difficulty with balance and coordination
Answer B: Loss of vision
Rationale: The occipital lobe, located at the posterior of the brain, is the
primary visual processing center. Damage here leads to visual deficits.
,2. Which structure connects the left and right cerebral hemispheres,
allowing communication between them?
A) Corpus callosum
B) Thalamus
C) Pons
D) Septum pellucidum
Answer A: Corpus callosum
Rationale: The corpus callosum is a large bundle of white matter tracts
(axons) that facilitates interhemispheric communication.
3. The primary somatosensory cortex, responsible for processing touch,
temperature, and pain, is located in which lobe?
A) Frontal lobe
B) Parietal lobe
C) Occipital lobe
D) Temporal lobe
Answer B: Parietal lobe
Rationale: The primary somatosensory cortex is located in the postcentral
gyrus of the parietal lobe.
,4. Which lobe of the brain is primarily responsible for motor control,
decision making, and problem-solving?
A) Frontal lobe
B) Parietal lobe
C) Occipital lobe
D) Temporal lobe
Answer A: Frontal lobe
Rationale: The frontal lobe contains the primary motor cortex and is
responsible for higher cognitive functions.
5. Which structure is responsible for relaying sensory information to the
cerebral cortex?
A) Hypothalamus
B) Thalamus
C) Pons
D) Medulla oblongata
Answer B: Thalamus
Rationale: The thalamus acts as a sensory relay station, directing sensory
input to the appropriate cortical areas.
, 6. Which brain structure is responsible for maintaining homeostasis by
regulating body temperature, hunger, and thirst?
A) Thalamus
B) Hypothalamus
C) Pons
D) Cerebellum
Answer B: Hypothalamus
Rationale: The hypothalamus is the master regulator of homeostasis,
controlling autonomic functions and endocrine activity.
7. Which structure is responsible for coordination, balance, and fine motor
movement?
A) Cerebrum
B) Brainstem
C) Cerebellum
D) Thalamus
Answer C: Cerebellum
Rationale: The cerebellum coordinates voluntary movements, maintains
posture, and regulates balance.
