,Question 1
Which of the following is primarily controlled by the somatic
division of the peripheral nervous system?
A. Voluntary movement of skeletal muscles
B. Regulation of heart rate during stress
C. Reflexive activation of digestive secretions
D. Auditory sensory transduction
Correct Answer: A
Rationale: The somatic division of the peripheral nervous
system controls voluntary skeletal muscle movements (e.g.,
moving your arm). Option A is correct because it describes
voluntary motor control, a function of the somatic nervous
system. Option B is incorrect; regulating heart rate during stress
is a function of the autonomic nervous system (sympathetic
division). Option C is incorrect; digestive secretions are
controlled by the parasympathetic division of the autonomic
nervous system, not somatic. Option D is incorrect; auditory
sensory transduction (carried by the vestibulocochlear nerve) is
part of the sensory pathways (special senses) of the peripheral
nervous system but not under the voluntary somatic motor
division.
Question 2
, Which type of glial cell is responsible for myelinating axons in
the central nervous system?
A. Schwann cell
B. Oligodendrocyte
C. Astrocyte
D. Microglia
Correct Answer: B
Rationale: Oligodendrocytes produce the myelin sheath for
axons within the central nervous system. This myelin speeds
conduction of neural signals in the brain and spinal cord. Option
A is incorrect; Schwann cells myelinate axons in the peripheral
nervous system, not the CNS. Option C is incorrect; astrocytes
support neurons and help form the blood–brain barrier but do
not myelinate axons. Option D is incorrect; microglia function as
immune cells in the CNS and do not form myelin. Only
oligodendrocytes form myelin sheaths around central axons.
Question 3
Damage to which lobe of the brain would most likely impair
processing of auditory information?
A. Parietal lobe
B. Occipital lobe
C. Temporal lobe
D. Frontal lobe
