Sample item

What is the main function of myelin around many axons?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Increase conduction velocity

The core Neurophysiology relationship supports Increase conduction velocity; it is the response that directly accounts for the structural location or physiological change described.

Option by option

  • A. Increase conduction velocity (correct)

    Correct. Increase conduction velocity is directly supported by the central clue.

  • B. Digest proteins

    Digest proteins does not fulfill the structural or functional role requested.

  • C. Store glycogen

    Store glycogen is not consistent with the key finding in the stem.

  • D. Produce neurotransmitter

    Produce neurotransmitter is associated with a different neurophysiology relationship.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study Neurophysiology?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
