Sample item

Which hormone is released from the posterior pituitary during water deprivation?

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

The answer and the reasoning

D. Vasopressin

Vasopressin is released from the posterior pituitary when plasma osmolality rises, increasing renal water reabsorption and concentrating urine.

Option by option

  • A. Thyroid-stimulating hormone

    TSH is released by the anterior pituitary.

  • B. Insulin

    Insulin regulates glucose metabolism.

  • C. Cortisol

    Cortisol is a glucocorticoid from adrenal cortex.

  • D. Vasopressin (correct)

    Correct: vasopressin conserves water during water deprivation.

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 Endocrine physiology?

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.
