Clinical/Applied Stem:
A 19-year-old sprinter develops sudden foot drop after
repeated compression near the fibular head. He also has
numbness over the dorsum of the foot in the same distribution.
The deficit is confined to one named structure outside the
central nervous system.
Options:
A. Corticospinal tract
B. Peripheral nerve
,C. Spinal cord white matter tract
D. Brainstem nucleus
Correct Answer: B. Peripheral nerve
Rationales:
B. Peripheral nerve — A single named nerve in the PNS can
produce both motor and sensory loss in its distribution. The
foot drop plus localized numbness fits a mixed peripheral nerve
injury.
A. Corticospinal tract — This would usually produce an
upper motor neuron pattern and would not cause isolated
sensory loss.
C. Spinal cord white matter tract — A cord lesion is more
likely to affect long tracts below the lesion and usually produces
broader patterns than one local nerve territory.
D. Brainstem nucleus — A nucleus is a CNS gray-matter
structure and would not typically cause an isolated peripheral
distribution like this.
Teaching Point:
Mixed motor-sensory deficits in one distribution often localize
to a peripheral nerve.

Ch. 1 — General Organization — Dorsal Root Ganglion
Clinical/Applied Stem:
A patient with shingles later develops persistent burning pain in
one dermatomal region. The clinician explains that the virus
reactivated in a sensory neuron cell body located outside the
spinal cord. Which structure was affected?
Options:
A. Anterior horn cell
B. Dorsal root ganglion
C. Cortical sensory nucleus
D. Ventral horn
Correct Answer: B. Dorsal root ganglion
Rationales:
B. Dorsal root ganglion — Primary sensory neuron cell
bodies reside in dorsal root ganglia, which are part of the PNS.
Reactivation there explains dermatomal pain and sensory
symptoms.
A. Anterior horn cell — This contains lower motor neuron
cell bodies, not sensory neuron cell bodies.
C. Cortical sensory nucleus — Sensory cell bodies are not
located in the cortex; cortex contains processing areas, not
primary sensory ganglia.
D. Ventral horn — Ventral horn contains motor neuron cell
bodies, not sensory neuron cell bodies.
, Teaching Point:
Primary sensory neuron cell bodies sit in dorsal root ganglia.

3️⃣ Reference
Ch. 1 — General Organization — Nucleus vs Ganglion
Clinical/Applied Stem:
A student is reviewing a peripheral autonomic pathway and
asks what you call a cluster of neuron cell bodies located
outside the central nervous system. The instructor emphasizes
that terminology changes depending on whether the cluster is
in the CNS or PNS.
Options:
A. Nucleus
B. Ganglion
C. Tract
D. Fasciculus
Correct Answer: B. Ganglion
Rationales:
B. Ganglion — A collection of neuronal cell bodies in the
PNS is called a ganglion. This is a core organizational distinction
in neuroanatomy.
