NCS PRACTICE EXAM 2026/2027 | NEUROLOGIC
CLINICAL SPECIALIST | 75 VERIFIED Q&A | DETAILED
RATIONALES | PASS GUARANTEED – A+ GRADED
SECTION 1: FOUNDATION SCIENCES & NEUROANATOMY - Questions 1-15
Q1: Neurotransmitter – Dopamine Pathways
The student is reviewing neurotransmitters. The nigrostriatal dopamine pathway is primarily
involved in:
A. Regulation of mood and emotion
B. Control of voluntary movement
C. Regulation of prolactin secretion
D. Modulation of pain perception
Correct Answer: B
Rationale: The nigrostriatal pathway projects from the substantia nigra to the striatum and is critical
for motor control. Its degeneration is the hallmark of Parkinson's disease. Option A describes the
mesolimbic pathway. Option C describes the tuberoinfundibular pathway. Option D is not a primary
function of this pathway. [100% CORRECT]
Q2: Spinal Cord Tracts – Spinocerebellar
The student is reviewing spinal tracts. The dorsal spinocerebellar tract carries information about:
A. Pain and temperature from the contralateral side
B. Proprioception from the ipsilateral lower limb
C. Fine touch from the contralateral side
D. Motor commands to the lower limb
Correct Answer: B
Rationale: The dorsal spinocerebellar tract transmits unconscious proprioceptive information from
muscle spindles and Golgi tendon organs of the ipsilateral lower limb to the cerebellum for
coordination. [100% CORRECT]
Q3: Cranial Nerves – Trigeminal
The student is reviewing cranial nerves. A patient reports loss of sensation over the lower jaw and
difficulty chewing. Which cranial nerve is most likely affected?
A. Facial (VII)
B. Trigeminal (V)
,2
C. Glossopharyngeal (IX)
D. Hypoglossal (XII)
Correct Answer: B
Rationale: The trigeminal nerve (CN V) provides sensation to the face and innervates the muscles of
mastication. The mandibular division (V3) supplies the lower jaw and chewing muscles. [100%
CORRECT]
Q4: Cerebral Cortex – Homunculus
The student is reviewing cortical organization. The motor homunculus demonstrates that:
A. The hands and face have disproportionately large representation
B. The trunk has the largest representation
C. The legs have the largest representation
D. All body parts have equal representation
Correct Answer: A
Rationale: The motor homunculus shows that body regions with finer motor control (hands, face,
tongue) have larger cortical representations. [100% CORRECT]
Q5: Neuroplasticity – Critical Periods
The student is reviewing neuroplasticity. Which statement about critical periods is most accurate?
A. Critical periods are limited to childhood and do not exist in adults
B. Critical periods are times of heightened plasticity when specific experiences are necessary for
normal development
C. Critical periods are permanent and cannot be altered
D. Critical periods only apply to sensory systems
Correct Answer: B
Rationale: Critical periods are developmental windows during which the nervous system is
particularly sensitive to specific experiences. While most prominent in early life, some plasticity
persists throughout adulthood. [100% CORRECT]
Q6: Autonomic Nervous System – Receptors
The student is reviewing autonomic pharmacology. Stimulation of beta-1 adrenergic receptors
primarily causes:
A. Bronchodilation
B. Increased heart rate and contractility
C. Pupillary constriction
D. Increased gastrointestinal motility
Correct Answer: B
, 3
Rationale: Beta-1 receptors are located primarily in the heart. Their stimulation increases heart rate
(chronotropy) and contractility (inotropy). Beta-2 receptors cause bronchodilation. Alpha-1
receptors cause pupillary dilation. [100% CORRECT]
Q7: Neuroanatomy – Internal Capsule
The student is reviewing neuroanatomy. A lesion in the posterior limb of the internal capsule most
likely causes:
A. Contralateral hemiparesis and sensory loss
B. Ipsilateral ataxia
C. Bilateral visual field loss
D. Aphasia
Correct Answer: A
Rationale: The posterior limb of the internal capsule contains the corticospinal tract and
thalamocortical fibers. A lesion here causes contralateral hemiparesis and hemisensory loss. [100%
CORRECT]
Q8: Blood Supply – Circle of Willis
The student is reviewing cerebral circulation. The circle of Willis is formed by anastomoses between
which two arterial systems?
A. Internal carotid and vertebrobasilar
B. External carotid and vertebral
C. Middle cerebral and posterior cerebral
D. Anterior cerebral and middle cerebral
Correct Answer: A
Rationale: The circle of Willis connects the internal carotid system (anterior circulation) with the
vertebrobasilar system (posterior circulation), providing collateral blood flow. [100% CORRECT]
Q9: Neurotransmitters – Acetylcholine
The student is reviewing neurotransmitters. Acetylcholine is the primary neurotransmitter at which
of the following?
A. Neuromuscular junction
B. Sympathetic postganglionic synapses
C. Adrenal medulla
D. Sensory afferents
Correct Answer: A
Rationale: Acetylcholine is released at the neuromuscular junction to initiate muscle contraction.
Sympathetic postganglionic neurons release norepinephrine (except sweat glands). [100% CORRECT]
