Sample item

What neurotransmitter is released at the skeletal neuromuscular junction?

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

The answer and the reasoning

D. Acetylcholine

The relevant Neurophysiology principle makes Acetylcholine the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. GABA

    GABA is not supported by the key clue provided in this item.

  • B. Serotonin

    Serotonin is associated with a different anatomical or physiological role.

  • C. Dopamine

    Dopamine does not correspond to the structure or response being tested.

  • D. Acetylcholine (correct)

    Correct. Acetylcholine directly follows from the core 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.
