Which hormonal pair shares a common hypothalamic releasing factor?
Correct answer: D. FSH and LH
- A. STH and LH
- B. FSH and STH
- C. ACTH and LH
- D. FSH and LH
Explanation
Explanation:FSH and LH are both gonadotropins that are involved in the regulation of reproductive function. They are produced by the anterior pituitary gland and are regulated by the hypothalamic hormone GnRH.STH (somatotropin hormone, also known as growth hormone) and LH (luteinizing hormone) do not share a common hypothalamic-releasing factor. STH is regulated by the hypothalamic hormone GHRH (growth hormone-releasing hormone), while LH is regulated by the hypothalamic hormone GnRH (gonadotropin-releasing hormone).FSH (Follicle-stimulating hormone) and STH don't share a common hypothalamic releasing factor. FSH is regulated by the hypothalamic hormone GnRH, while STH is regulated by GHRH.FSH (Follicle-stimulating hormone) and STH don't share a common hypothalamic releasing factor. FSH is regulated by the hypothalamic hormone GnRH, while STH is regulated by GHRH.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
