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.
8. Which of the following correctly lists the meninges from superficial to deep?
A) Pia mater, arachnoid mater, dura mater
B) Dura mater, arachnoid mater, pia mater
C) Arachnoid mater, dura mater, pia mater
D) Dura mater, pia mater, arachnoid mater
Answer B: Dura mater, arachnoid mater, pia mater
Rationale: The meninges from superficial to deep are dura mater, arachnoid mater, and pia mater.
9. Cerebrospinal fluid (CSF) is produced by which structure?
A) Arachnoid villi
B) Choroid plexus
C) Fourth ventricle
D) Subarachnoid space
Answer B: Choroid plexus
Rationale: CSF is produced by the choroid plexus located in the lateral, third, and fourth ventricles.
10. Which of the following is a function of cerebrospinal fluid (CSF)?
A) Cushioning the brain and spinal cord
B) Producing neurotransmitters
C) Generating action potentials
D) Storing memories
Answer A: Cushioning the brain and spinal cord
Rationale: CSF provides buoyancy, protection, and chemical stability for the central nervous system.
