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.
Premenstrual syndrome (PMS) can include mood swings, fluid retention (edema), anxiety, backache and joint pain, food cravings, and other symptoms. PMS usually develops after ovulation and lasts until just before or just after menstruation begins. Although the precise cause of PMS is unknown, it seems clearly related to the cyclic production of ovarian hormones. After reviewing Figure 16.3, suggest which hormonal changes may trigger PMS. Figure 16.3 Animated! Hormones govern the menstrual and ovarian cycles. A GnRH from the hypothalamus stimulates the anterior pituitary to secrete FSH and LH. B FSH and LH stimulate a follicle to grow, an oocyte to mature, and the ovaries to secrete progesterone and estrogens that stimulate the endometrium to rebuild. C A midcycle LH surge triggers ovulation and the formation of a corpus luteum. D Progesterone and some estrogens released by the corpus luteum maintain the endometrium, but if no pregnancy occurs, they stop being released and the corpus luteum breaks down. ( Cengage Learning)
Identify 3 effects of progesterone on pregnancy. Select one or more: O a. This causes the uterus to remain contracted after delivery to reduce blood loss from the placental site O b.
