1. Reference: Ch. 1 — General Organization — CNS vs PNS
Clinical/Applied Stem:
A 29-year-old man develops numbness and weakness after a motorcycle accident. Imaging shows injury
outside the spinal cord, involving a structure that carries motor and sensory information between the
body and the central nervous system. Which structure is most likely injured?
Options:
A. Peripheral nervous system
B. Cerebral cortex
C. Basal ganglia
D. Cerebellar cortex
Correct Answer: A. Peripheral nervous system
Rationale — Correct Answer:
The peripheral nervous system includes nerves and ganglia outside the brain and spinal cord. Trauma to
this system can produce combined sensory and motor deficits in a distribution that follows a nerve,
plexus, or root.
,Rationale — Incorrect Options:
B. The cerebral cortex is part of the CNS, not the structure directly described here.
C. Basal ganglia lesions cause movement disorders, not a peripheral trauma pattern.
D. Cerebellar cortex injury causes coordination problems, not combined peripheral sensory-motor loss.
Teaching Point:
Peripheral lesions follow nerve/root distributions; CNS lesions do not.

2. Reference: Ch. 1 — General Organization — Gray Matter vs White Matter
Clinical/Applied Stem:
A patient has a disorder that primarily destroys neuron cell bodies and synapses rather than long
myelinated axons. Clinically, this would most directly affect the “processing” regions of the nervous
system. Which tissue is primarily involved?
Options:
A. White matter
B. Gray matter
C. Myelin sheath only
D. Meninges
Correct Answer: B. Gray matter
Rationale — Correct Answer:
Gray matter contains neuronal cell bodies, dendrites, and synapses. Damage here disrupts local
processing and integration more than long-range conduction.
Rationale — Incorrect Options:
A. White matter is composed mainly of myelinated axons that carry signals over distance.
C. Myelin is part of white matter architecture, but the stem emphasizes cell bodies and synapses.
D. Meninges are protective coverings, not neural tissue.
Teaching Point:
Gray matter processes; white matter transmits.

3. Reference: Ch. 1 — General Organization — Dorsal Root vs Ventral Root
Clinical/Applied Stem:
After a lumbar disc herniation, a patient has severe radicular pain and loss of sensation in a dermatomal
pattern, but motor strength remains normal. The compressed structure most likely carries afferent
information into the spinal cord. Which is it?
,Options:
A. Ventral root
B. Dorsal root
C. Anterior horn cell
D. Peripheral neuromuscular junction
Correct Answer: B. Dorsal root
Rationale — Correct Answer:
The dorsal root carries sensory afferent fibers into the spinal cord. Compression here causes sensory loss
and radicular pain without primary motor weakness.
Rationale — Incorrect Options:
A. The ventral root carries motor efferent fibers, so it would more likely produce weakness.
C. Anterior horn cell disease causes lower motor neuron signs, not isolated dermatomal sensory loss.
D. The neuromuscular junction causes fatigable weakness, not dermatomal pain and numbness.
Teaching Point:
Dorsal root = sensory in; ventral root = motor out.

4. Reference: Ch. 1 — General Organization — Ventral Root / Lower Motor Neuron
Clinical/Applied Stem:
A patient has flaccid weakness, muscle atrophy, and diminished reflexes in one leg after a lesion affecting
the final common pathway to skeletal muscle. Sensation is intact. Which structure is most likely
damaged?
Options:
A. Ventral root
B. Posterior column
C. Parietal cortex
D. Spinothalamic tract
Correct Answer: A. Ventral root
Rationale — Correct Answer:
The ventral root contains lower motor neuron efferents destined for skeletal muscle. Injury produces
flaccid weakness and areflexia without primary sensory loss.
Rationale — Incorrect Options:
B. Posterior column lesions affect vibration and proprioception, not pure motor output.
C. Parietal cortex lesions produce cortical sensory deficits, not isolated flaccid weakness.
D. Spinothalamic tract lesions impair pain and temperature, not motor strength.
, Teaching Point:
Lower motor neuron lesions cause weakness plus loss of reflexes.

5. Reference: Ch. 1 — General Organization — Upper vs Lower Motor Neuron
Clinical/Applied Stem:
A 67-year-old woman has spasticity, hyperreflexia, and an upgoing plantar response after a stroke. Her
muscle bulk is preserved early in the course. Which pathway is most likely involved?
Options:
A. Corticospinal tract
B. Peripheral sensory nerve
C. Neuromuscular junction
D. Dorsal root ganglion only
Correct Answer: A. Corticospinal tract
Rationale — Correct Answer:
The corticospinal tract is the major descending motor pathway and is part of the upper motor neuron
system. Lesions produce spasticity, hyperreflexia, and pathologic reflexes.
Rationale — Incorrect Options:
B. Sensory nerve injury does not produce classic upper motor neuron signs.
C. Neuromuscular junction disorders cause fatigable weakness, not hyperreflexia.
D. Dorsal root ganglion lesions are sensory and would not explain spasticity.
Teaching Point:
UMN lesions cause spasticity and hyperreflexia.

6. Reference: Ch. 1 — General Organization — Spinal Cord Level Localization
Clinical/Applied Stem:
A patient has weakness in both legs, a band-like sensory change around the trunk, and bowel
dysfunction after trauma. The deficits begin below one specific horizontal level. What is the best
localization?
Options:
A. Peripheral nerve
B. Spinal cord
C. Neuromuscular junction
D. Muscular dystrophy
