,Question 1
Which type of glial cell is responsible for forming myelin in the
central nervous system (CNS)?
A. Astrocytes
B. Oligodendrocytes
C. Schwann cells
D. Microglia
Correct Answer: B
Rationale:
Oligodendrocytes form the myelin sheath around axons in the
CNS, insulating neurons for faster signal conduction. Astrocytes
(Option A) support neurons but do not form myelin. Schwann
cells (Option C) form myelin in the peripheral nervous system
(PNS), not the CNS. Microglia (Option D) are immune cells that
clean up debris and pathogens; they do not create myelin.
Question 2
The dura mater infolding that separates the two cerebral
hemispheres is known as the:
A. Tentorium cerebelli
B. Falx cerebri
C. Falx cerebelli
D. Diaphragma sella
Correct Answer: B
, Rationale:
The falx cerebri is the dural fold that runs in the midline
between the left and right cerebral hemispheres, fully
separating them down to the corpus callosum. The tentorium
cerebelli (Option A) is a horizontal dural shelf separating the
cerebrum from the cerebellum. The falx cerebelli (Option C)
separates the two cerebellar hemispheres, not the cerebral
hemispheres. The diaphragma sella (Option D) is a small dural
membrane covering the pituitary gland; it is not involved in
separating the cerebral hemispheres.
Question 3
Which cranial nerve carries auditory (hearing) information from
the inner ear to the brain?
A. Facial (VII)
B. Trigeminal (V)
C. Glossopharyngeal (IX)
D. Vestibulocochlear (VIII)
Correct Answer: D
Rationale:
The vestibulocochlear nerve (Cranial Nerve VIII) is responsible
for carrying auditory signals from the cochlea of the inner ear to
the brain. The Facial nerve (Option A, VII) is primarily motor for
facial muscles and carries some taste fibers, not auditory
signals. The Trigeminal nerve (Option B, V) carries sensory
