Q.118) Which of the following hormones released from the pituitary is synthesised in the
hypothalamus?
A) (1) Adenoeorticotrophic hormone (ACTH)
B) (2) Luteinizing hormone (LH)
C)(3) Anti-diuretic hormone (ADH)
D) (4) Follicle-stimulating hormone (FSH)
Q.118) ADH (Anti-diuretic hormone), also known as vasopressin, is synthesized in the hypothalamus (specifically in the supraoptic and paraventricular nuclei).
Although it is made in the hypothalamus, it is stored and released from the posterior pituitary (neurohypophysis).
Let’s see why the others are incorrect:
(1) ACTH, (2) LH, and (4) FSH are all synthesized and secreted by the anterior pituitary (adenohypophysis), not the hypothalamus.
Hence, the correct answer is option (3): Anti-diuretic hormone (ADH).
