,Question 1
The somatic nervous system primarily controls ________.
A. involuntary functions such as heart rate and digestion
B. voluntary contractions of skeletal muscles
C. sensory feedback from the internal organs
D. hormonal secretion by endocrine glands
Correct Answer: B
Rationale: The somatic nervous system is responsible for
voluntary movement of skeletal muscles. It does not control
involuntary functions (Option A) – those are regulated by the
autonomic nervous system. It is not primarily involved in
sensory input from internal organs (Option C) or hormone
release (Option D), which involve other systems.
Question 2
Which glial cell type is responsible for forming the myelin
sheath around axons in the peripheral nervous system?
A. Astrocyte
B. Oligodendrocyte
C. Schwann cell
D. Microglia
Correct Answer: C
, Rationale: Schwann cells (Option C) wrap around axons in the
peripheral nervous system (PNS) to form the myelin sheath.
Astrocytes (Option A) are supportive cells in the central nervous
system (CNS), not involved in myelination. Oligodendrocytes
(Option B) myelinate axons in the CNS, not the PNS. Microglia
(Option D) are immune cells in the CNS and do not form myelin.
Question 3
Nerve fibers that carry sensory information toward the central
nervous system are called ________ fibers.
A. efferent
B. afferent
C. internuncial
D. association
Correct Answer: B
Rationale: Afferent fibers (Option B) carry sensory signals
toward the CNS. Efferent fibers (Option A) carry motor signals
away from the CNS. “Internuncial” (Option C) is an old term not
used here. Association fibers (Option D) refer to connections
within the brain hemispheres, not to peripheral sensory
pathways.
Question 4
A lesion of which cranial nerve results in paralysis of the
muscles of facial expression?
