,Question 1
Which part of a neuron primarily receives incoming signals?
A. Axon
B. Soma (cell body)
C. Dendrite
D. Myelin sheath
Correct Answer: C
Rationale: The dendrites are the branch-like extensions of a
neuron that receive synaptic inputs from other neurons.
Incoming chemical or electrical signals are detected by
dendrites, which then transmit those signals toward the soma
(cell body). Option A is incorrect because the axon transmits
signals away from the soma, not toward it. Option B is incorrect
because the soma integrates incoming signals but does not
primarily receive them; it contains the nucleus but the
dendrites are the main receivers. Option D is incorrect because
the myelin sheath insulates axons and speeds conduction; it
does not receive incoming signals.
Question 2
Which of the following structures are components of the
central nervous system (CNS)?
A. Cranial nerves and spinal nerves
B. Brain and spinal cord
, C. Autonomic ganglia and plexuses
D. Sensory receptors in the periphery
Correct Answer: B
Rationale: The CNS consists of the brain and spinal cord. The
brain and spinal cord form the “control centers” for processing
sensory information and generating motor commands. Option A
is incorrect because cranial and spinal nerves are part of the
peripheral nervous system (PNS), not the CNS. Option C is
incorrect because autonomic ganglia (clusters of nerve cell
bodies) are located in the PNS. Option D is incorrect because
peripheral sensory receptors lie outside the CNS and send
information into the CNS but are not CNS components.
Question 3
Which division of the nervous system controls voluntary skeletal
muscle activity?
A. Sympathetic division of the autonomic system
B. Parasympathetic division of the autonomic system
C. Somatic nervous system
D. Central nervous system
Correct Answer: C
Rationale: Voluntary control of skeletal muscles is mediated by
the somatic nervous system. The somatic division carries motor
commands from the CNS to skeletal muscles that are under
conscious control. Option A and B are incorrect because the
