,Question 1
Which of the following correctly lists the meningeal layers from
outermost to innermost?
A. Dura mater, arachnoid mater, pia mater
B. Arachnoid mater, dura mater, pia mater
C. Pia mater, arachnoid mater, dura mater
D. Dura mater, pia mater, arachnoid mater
Correct Answer: A
Rationale: The three cranial meninges from superficial to deep
are dura mater (tough outer layer), arachnoid mater (middle
web-like layer), and pia mater (innermost layer adherent to the
brain). Option A correctly lists them in order. Option B is
incorrect because the arachnoid is not outermost. Option C is in
reverse order. Option D is incorrect because pia is inner and
cannot lie between dura and arachnoid. The correct ordering is
widely described in neuroanatomy references (outer dura, then
arachnoid, then pia).
Question 2
Which type of glial cell produces the myelin sheath for central
nervous system (CNS) neurons?
A. Oligodendrocyte
B. Astrocyte
, C. Microglial cell
D. Schwann cell
Correct Answer: A
Rationale: Oligodendrocytes are the CNS glial cells that wrap
axons in myelin. In contrast, Schwann cells (Option D) myelinate
axons in the peripheral nervous system. Astrocytes (Option B)
provide metabolic support and help form the blood–brain
barrier, but do not form myelin. Microglia (Option C) are
immune cells in the CNS and do not myelinate. The cited source
states “myelin is formed via oligodendrocytes and Schwann
cells in the central and peripheral nervous systems,
respectively”, confirming oligodendrocyte as correct for the
CNS.
Question 3
Which division of the autonomic nervous system is primarily
responsible for the “fight or flight” response?
A. Sympathetic nervous system
B. Parasympathetic nervous system
C. Enteric nervous system
D. Somatic nervous system
Correct Answer: A
Rationale: The sympathetic division of the autonomic nervous
system mobilizes the body for “fight or flight” by increasing
