Question

Which of the following hormones released from the pituitary is actually synthesized in the hypothalamus?

1. A. Luteinizing hormone (LH)
2. B. Anti-diuretic hormone (ADH) (Correct answer)
3. C. Follicle-stimulating hormone (FSH)
4. D. Adrenocorticotropic hormone (ACTH)

Correct Answer

Option B — Anti-diuretic hormone (ADH)

Detailed Solution & Explanation

The correct answer is Anti-diuretic hormone (ADH).

Key Points

• The neurohypophysis (posterior pituitary) only stores and releases oxytocin and vasopressin (ADH), which are actually synthesised in the hypothalamus and transported axonally.
• FSH, LH and ACTH are produced by the anterior pituitary (pars distalis) itself.
