,Question 1
Which of the following structures is part of the peripheral
nervous system (PNS)?
A. Cerebral cortex
B. Thalamus
C. Pons
D. Dorsal root ganglion
Correct Answer: D
Rationale: Option D is correct because dorsal root ganglia are
groups of sensory neuron cell bodies located in the peripheral
nervous system. In contrast, the cerebral cortex (A), thalamus
(B), and pons (C) are all parts of the central nervous system
(CNS) – they reside within the brain or brainstem.
Why Option A is incorrect: The cerebral cortex is part of the
brain (CNS), not the PNS.
Why Option B is incorrect: The thalamus is a deep brain
structure in the diencephalon (CNS), not in the PNS.
Why Option C is incorrect: The pons is in the brainstem (CNS),
not in the PNS.
Question 2
Which of the following best describes the autonomic nervous
system (ANS)?
A. It controls voluntary skeletal muscle movements.
, B. It regulates involuntary functions like heart rate and
digestion.
C. It is a division of the central nervous system.
D. It primarily processes sensory input.
Correct Answer: B
Rationale: Option B is correct because the ANS controls
involuntary physiological processes (such as heart rate, blood
pressure, respiration, digestion). The ANS is a component of the
peripheral nervous system that regulates automatic body
functions. Option A is incorrect because voluntary control of
skeletal muscles is mediated by the somatic (not autonomic)
nervous system. Option C is incorrect because the ANS is part of
the peripheral nervous system (not the CNS). Option D is
incorrect because the ANS includes both afferent (sensory) and
efferent (motor) pathways for visceral organs; it is not
exclusively sensory.
Question 3
Which of the following adult brain structures develops from the
hindbrain (rhombencephalon)?
A. Cerebral cortex (frontal/parietal lobes)
B. Thalamus
C. Cerebellum
D. Hippocampus
Correct Answer: C
Rationale: Option C is correct because the cerebellum arises
