The secretion of the following pituitary hormones is controlled by hypothalamus
Open in App
Solution
The correct option is D Luteinizing hormone (LH), corticotropin (ACTH) and thyrotropin (TSH)
Option A is incorrect as cortisol is the glucorticoid released in response to stress by adrenal cortex, not by pituitary gland. Option B is incorrect as progesterone is the female sex hormone which is released by ovaries, not by pituitary gland. Option C is incorrect as vasopressin is produced by hypothalamus but is stored and released into the bloodstream via posterior pituitary. LH, ACTH and TSH are the anterior pituitary hormones which are regulated by hypothalamic releasing hormones and hypothalamic inhibiting hormones via negative feedback control mechanism. Thus, option D is correct.
