This causes the uterus to remain contracted after delivery to reduce blood loss from the placental site O b. This is produced when the ovarian follicle that encloses the developing egg forms a structure called the corpus luteum O c. This decreases bladder tone leading to an increased risk of urinary infection O d. This prepares the body for pregnancy. It acts as an appetite stimulant Identify 1 effect of the hormone vasopressin in pregnancy. Select one: O a.

- How will you explain the role of Gonadotropin Releasing Hormone (GnRH)? The GnRH is a/an: follicle stimulator that will mature the egg cell. testes stimulator that will synthesize testosterone. С. 8. A. B. pituitary Gland stimulator that will produce FSH and LH. D. ovary stimulator that will produce sex steroid hormones. Which of these roles of hormones explains the changes in the physical appearance of the extemal genitalia of the male and female reproductive part at the onset of puberty? 9. А. Stimulation of follicle alone. В. Production of sperm and egg cell. С. Regulation of the production of GNRH D. Development of male and female characteristics. Which of the following hormone pairing will best explain why men and women have unique physical structures? 10. А. (Testosterone, Estrogen) C. (Progesterone, Adrenaline) В. (Progesterone, Estrogen) D. (Testosterone, Progesterone) What type of feedback mechanism is described when progesterone and estrogen levels drop after menstruation,…arrow_forwardWhich of the following rows indicates this pregnancy hormone and the correct location of production?

Hormone - Progesterone, Location of production up until 10 weeks - Trophoblast, Location of production after 10 weeks - Placentaarrow_forwardDuring the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum? Select one: a. The corpus luteum produces relaxin, which thickens the endometrium. b. The corpus luteum ensures that the endometrium does not break down during the first trimester. c. The corpus luteum supports the formation of the placenta. d. The chorion forms the fetal part of the placenta, and the corpus luteum supports the maternal part of the placenta.arrow_forward
- What is a potential consequence of embryonic exposure to endocrine-disrupting compounds that can bind to estrogen receptors? Select one: a. Increased growth rate and early birth b. Decrease in size of developing testes c. Increased rate of ovulation d. Decreased sperm count e. Choices B and D are correctarrow_forwardSertoli cells produce androgen binding protein. The purpose of this androgen binding protein is to : (select one) a. Transport testosterone to the developing germ cells b. Increase the clearance rate of testosterone c. Prevent the germs cells being exposed to toxic concentrations of testosterone d. Manufacture androgens e. Transport testosterone to the capillariesarrow_forwardWhich of the following statements does NOT correctly describe the events following fertilization? Select one: a. Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.arrow_forward
- Which of the following hormones in pregnancy is INCORRECTLY matched with its description? a. Estrogen - promotes growth of the uterus b. Insulin - target cells are slightly less responsive c. GnRH - is at low levels due to negative feedback from estrogen & progesterone d. hCG - promotes cell division within the growing embryo e. Progesterone - prohibits uterine contractionsarrow_forwardHuman chorionic gonadotropin (hCG) hormone is produced by a fertilized egg in order to maintain elevated levels of estrogen and progesterone. hCG is also used to induce ovulation during IVF procedures and is known to stimulate the production of testosterone in the testes.
