Endocrine physiology: practice question

The best answer is C, Oxytocin. Oxytocin is released from the posterior pituitary and stimulates uterine smooth-muscle contraction during labor as well as milk ejection after delivery.

Prolactin primarily stimulates milk synthesis in the breast.

FSH promotes follicular development in the ovary.

Cortisol is a stress hormone from the adrenal cortex.

It tests Endocrine physiology in Physiology. The correct option holds because: Correct: oxytocin promotes uterine contraction and milk ejection.

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.

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.

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.
