33. True or False. The hormones involved in the hypothalamic are non-tropic in nature
answer quickly please
This statement is false.
The hypothalamic hormones are tropic in nature.
Non-tropic hormones act on target cells or tissues directly, i.e. they are produced by endocrine glands, then transported through the blood to their target cells and induce effects on those cells. These hormones don't induce effects on other endocrine glands. But, hypothalamic hormones are known to control the activity of anterior pituitary, which is an endocrine gland. These hormones don't induce effects on cells or tissues directly. That's why hypothalamic hormones are not non-tropic in nature.
Hypothalamic hormones, that target other endocrine glands and control their hormone production, are called tropic hormones.
Few examples of hypothalamic hormones -
Corticotropin-releasing hormone - This hormone controls the production of ACTH (adrenocorticotropic hormone) from the anterior pituitary.
Growth hormone-releasing hormone - This hypothalamic hormone stimulates the production of growth hormones from the pituitary gland.
Gonadotropin-releasing hormone stimulates the production of FH (follicle-stimulating hormone) and LH (luteinizing hormone) from the anterior pituitary.
