Question
Chapter 25, Problem 5RQ
Summary Introduction
To determine:
The true statement about the luteinizing hormone (LH) and the follicle-stimulating hormone (FSH).
Introduction:
Hormones are designated as the chemo-messengers of the human body. They regulate various process by either stimulating or inhibiting and sometimes both. Pituitary gland is referred to as the master gland of the human body as the secretions of the pituitary regulate the secretions of other glands of the human body. However, the secretion of the pituitary gland is regulated by the hormones of the hypothalamus.

- Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.arrow_forwardMatch each hormone with its effect. oxytocin a. growth of facial hair testosterone b. uterus contracts LH c.
