MCQs (1–30)
THEORY-BASED QUESTIONS (1–15)
Q1.
Which bone forms the anterior cranial fossa and supports the frontal lobes?
A. Temporal
B. Sphenoid
C. Frontal
D. Occipital
E. Parietal
Answer: C. Frontal
Explanation:
• The frontal bone forms the anterior cranial fossa → supports frontal lobes
(executive function, motor planning).
• Also contains frontal sinus → clinically relevant in trauma.
Why others are wrong:
• A: Temporal → middle cranial fossa
• B: Sphenoid → central skull base
• D: Occipital → posterior cranial fossa
• E: Parietal → skull vault
Clinical correlation: Fracture here → frontal lobe deficits (personality, disinhibition)
Q2.
The middle cranial fossa primarily accommodates which structures?
,A. Cerebellum
B. Temporal lobes
C. Occipital lobes
D. Brainstem
E. Frontal lobes
Answer: B. Temporal lobes
Explanation:
• Middle cranial fossa houses temporal lobes → memory, auditory processing.
Others:
• A, D: posterior fossa
• C: posterior cranial fossa
• E: anterior cranial fossa
Clinical: Temporal bone fractures → CN VII, VIII damage → hearing loss + facial
paralysis
Q3.
The posterior cranial fossa contains all EXCEPT:
A. Cerebellum
B. Pons
C. Medulla
D. Temporal lobe
E. Fourth ventricle
Answer: D. Temporal lobe
Explanation:
• Posterior fossa = cerebellum + brainstem
• Temporal lobe = middle fossa
Clinical: Posterior fossa lesions → ataxia, cranial nerve deficits
, Q4.
Which foramen transmits the spinal cord?
A. Foramen ovale
B. Foramen rotundum
C. Jugular foramen
D. Foramen magnum
E. Optic canal
Answer: D. Foramen magnum
Explanation:
• Passage of medulla → spinal cord transition
• Also vertebral arteries
Clinical: Herniation here → respiratory arrest
Q5.
Which meningeal layer is tightly adherent to the skull?
A. Pia mater
B. Arachnoid mater
C. Dura mater (periosteal layer)
D. Dura mater (meningeal layer)
E. Subarachnoid space
Answer: C
Explanation:
• Periosteal dura = inner skull lining
Clinical: Epidural hematoma occurs between skull and dura
Q6.
The subarachnoid space contains:
