Question

antidiuretic hormone (adh) is produced by the ______ and secreted by the ______.
a) juxtaglomerular apparatus; juxtaglomerular apparatus
b) posterior pituitary; posterior pituitary
c) hypothalamus; anterior pituitary
d) hypothalamus; posterior pituitary

Explanation:

To solve this, we recall the physiology of ADH (Antidiuretic Hormone). ADH is synthesized (produced) by the hypothalamus and then stored and secreted by the posterior pituitary gland. Let's analyze each option:

• Option A: The juxtaglomerular apparatus is involved in renin production, not ADH. Eliminate A.
• Option B: The posterior pituitary does not produce ADH (it secretes it), so B is wrong.
• Option C: The anterior pituitary is not involved in ADH secretion. Eliminate C.
• Option D: Matches the correct production (hypothalamus) and secretion (posterior pituitary) of ADH.

Answer:

D. hypothalamus; posterior pituitary
