- 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.

- Describe the function of each of the following hormones in the uterine and ovarian cycles: GnRH, FSH, LH, estrogens, progesterone, and inhibin.Three of the steps of neuro endocrine mechanism in respect of parturition are mentioned below.Write the missing steps in proper sequence.(a) Signals originate from fully developed foetus and placenta.(b) ______________________________.(c) ______________________________.(d) Oxytocin causes strong uterine contraction(e) Uterine contraction stimulates further secretion of oxytocin.(f) ______________________________.A woman is in labor. The size of the fetus combined with the contractions of the uterine muscular layer stretches the uterine wall, stimulating stretch receptors in the cervix. Signals from these receptors are conducted through nerves to the hypothalamus/posterior pituitary. The hypothalamus/posterior pituitary releases oxytocin. The oxytocin travels through the blood and stimulates the smooth muscle layer of the uterus. Oxytocin has two effects on the uterine smooth muscle: It directly stimulates the smooth muscle to contract more frequently and more It causes the uterine wall to release prostaglandins, which increase the frequency and force of These effects push the fetus more forcefully into the cervix, stimulating the stretch receptors further. The receptors send additional impulses to the hypothalamus/posterior pituitary. The increased activation of the hypothalamus/posterior pituitary stimulates release of additional oxytocin, which further stimulates the uterus. This cycle of…

TestosteroneB. ProgestinC. GlucocorticoidsD. Chorionic gonadotropinE. Tamoxifen, clomiphene citrateThe primary purpose of gonadotropin-releasing hormone (GnRH) is to stimulate the : Breakdown of the endometrium in the menstrual flow . Development of the woman's breasts for lactation . Secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH ) from the anterior pituitary gland . Growth of pubic and axillary hair .
- For each hormone, select whether the hormone is increasing or decreasing at the beginning of parturition. In addition, select the correct effect that the change in hormone secretion causes. Hormone Levels Resulting Effect Increasing Decreasing Causes the endometrial layer to break away from the uterus Causes the endometrial layer to be maintained Increases uterine contractions Decreases uterine contractions Increases milk production in the mother's breasts Decrease milk production in the mother's breasts Hormone Hormone Levels Resulting Effect Estrogen Progesterone Oxytocin Prostaglandins ProlactinWhich of the following statements correctly describes the effects of increased testosterone? a. Increased levels of testosterone result in increased sperm production b. Increased levels of testosterone decreases the release of FSH and LH c. Increased levels of testosterone stimulates the release of GnRH d. Increased levels of testosterone stimulates the release of FSH and LH.Identify three major factors opposing the calming action of progesterone on the uterus.
