Neurological Assessment NCLEX Questions Questions
Question 1 of 5
Which of the following best describes the waxy-appearing material called myelin:
Correct Answer: D
Rationale: Myelin is a lipid-rich insulating layer around axons, formed by neuroglia (e.g., Schwann cells in PNS, oligodendrocytes in CNS), speeding signal conduction.
Question 2 of 5
From which layer of the embryo does the nervous system form?
Correct Answer: A
Rationale: The nervous system derives from the ectoderm via the neural plate, which forms the neural tube, unlike mesoderm (muscles, bones) or endoderm (gut).
Question 3 of 5
What structures does light pass through before reaching the primary visual cortex? (list in order)
Correct Answer: C
Rationale: Light path: cornea, aqueous humor, lens, vitreous humor, then retina (rods/cones, then ganglion cells), optic nerve, LGN, to V1; C is closest despite missing cornea.
Question 4 of 5
The basilar membrane
Correct Answer: C
Rationale: The basilar membrane is wider and less stiff at the apex, resonating with low frequencies, while the base handles high frequencies.
Question 5 of 5
Which pair of neurons is most similar in terms of their temporal firing patterns?
Correct Answer: C
Rationale: M-type (magnocellular) ganglion cells and Pacinian corpuscles are both rapidly adapting, responding to transient stimuli.
