  • 7. 
    In meiosis I, maternal and paternal chromosomes are segregated into separate daughter cells (true/ false)
  • 8. 
    FSH and LH are classified as (sex hormones / gonadotropins).
  • 9. 
    GnRH, which is secreted by the hypothalamus, stimulates the secretion of both FSH and LH from the anterior pituitary (true / false)
  • 10. 
    Spermatogenesis is stimulated by testosterone and (FSH / LH), which targets Sertoli cells.
  • 11. 
    The head of a sperm contains chromosomes and a(n) ________, a vesicle containing enzymes needed for fertilization
  • 12. 
    Fertilization usually occurs in the (uterus / uterine tube).
  • 13. 
    The second half of the ovarian cycle is called the (luteal / follicular) phase
  • 14. 
    The inner layer of the uterine wall is called the (endometrium / myometrium)
  • 15. 
    During the (proliferative / secretory) phase of the uterine cycle, the lining of the uterus thickens under influence of rising estrogen levels.
  • 16. 
    Ovulation is triggered by (FSH / LH).
  • 17. 
    The corpus luteum secretes estrogens and (LH / progesterone)
  • 18. 
    Degeneration of the corpus luteum causes hormonal changes that trigger (ovulation / menstruation).
  • 19. 
    Secretory phase uterine conditions are promoted by (estrogen / progesterone) which inhibits gonadotropin secretion during the last half of the ovarian cycle.
  • 20. 
    During the last 6 months of pregnancy, estrogens and progesterone are secreted by the (ovaries / placenta)
