,Question 1
Which two structures comprise the central nervous system
(CNS)?
A. Brain and spinal cord
B. Brain and peripheral nerves
C. Spinal cord and autonomic ganglia
D. Cranial nerves and spinal cord
Correct Answer: A
Rationale: The CNS consists of the brain and spinal cord, which
process and integrate information. The brain and spinal cord
together form the CNS. Option A correctly names these two
structures. Option B is incorrect because peripheral nerves are
part of the peripheral nervous system (PNS), not the CNS.
Option C is incorrect because autonomic ganglia are part of the
PNS (the autonomic nervous system) and are not in the CNS.
Option D is incorrect because cranial nerves are also part of the
PNS.
Question 2
The somatic nervous system primarily controls _____, whereas
the autonomic nervous system primarily controls _____.
A. Voluntary skeletal muscles; involuntary smooth muscle and
glands
B. Smooth muscle; skeletal muscle
, C. Sensory input; motor output
D. Reflexes; voluntary movements
Correct Answer: A
Rationale: The somatic nervous system innervates voluntary
skeletal muscles (e.g., those used for speech articulation and
limb movement), while the autonomic nervous system
innervates involuntary effectors like smooth muscle and glands.
Thus, Option A correctly contrasts voluntary skeletal muscle
control (somatic) with involuntary smooth muscle and gland
control (autonomic). Option B is incorrect because it swaps the
functions of the two systems. Option C is incorrect because
both systems have sensory and motor components; it does not
capture the voluntary vs. involuntary distinction. Option D is
incorrect because reflexes often involve autonomic or reflex
arcs, and voluntary movements are controlled by the somatic
system; the wording is confusing and does not correctly
describe the two systems.
Question 3
Which part of a neuron is primarily responsible for conducting
nerve impulses away from the cell body?
A. Axon
B. Dendrite
C. Nucleus
D. Soma (cell body)
