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

A Luteinizing hormone (LH)
B Anti-diuretic hormone (ADH)
C Follicle-stimulating hormone (FSH)
D Adrenocorticotropic hormone (ACTH)

Verified Solution

Answer & Solution

Correct Answer

(B) Anti-diuretic hormone (ADH)

Step-by-step Solution

Detailed explanation

Neurohypophysis i.e., posterior pituitary (Pars nervosa) stores and releases two hormones called oxytocin and vasopressin (Also called ADH i.e., antidiuretic hormone) which are actually synthesised by hypothalamus and are transported axonally to neurohypophysis. The pars distalis (anterior pituitary) produces follicle stimulating hormone (FSH), adrenocorticotropic hormone (ACTH) and luteinizing hormone (LH).

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
