Questions and Answers

All of the following statements referring to the uterine cycle are true EXCEPT:

  • FSH and LH directly promote development of the uterine endometrium (correct)
  • Menstruation occurs if fertilization does not happen
  • The endometrium enters its secretory phase after ovulation
  • The corpus luteum is maintained by a hormone secreted by the developing embryo if fertilization occurs

    • What are effects of estrogen?

    Growth of the breasts at puberty

    From where did the other two polar bodies arise if occasionally three polar bodies are found clinging to the mature ovum?

    The first polar body has also divided to produce two polar bodies.

    Study Notes

    Uterine Cycle Overview

    • All statements about the uterine cycle are true except that FSH and LH directly promote the development of the uterine endometrium.

    Effects of Estrogen

    • Estrogen promotes growth of breast tissue during puberty.

    Polar Bodies Formation

    • Three polar bodies may be found with a mature ovum; one arises from an unequal division of the ovum while the other two come from the division of the first polar body.

    Progesterone Function

    • Secretion of progesterone prepares the mammary glands for lactation.

    Corpus Luteum Maintenance

    • If fertilization occurs, the developing embryo secretes a hormone that maintains the corpus luteum.

    Genetic Variability

    • The statement that crossing over provides genetic variability in meiosis while independent assortment does so in mitosis is false.

    Spermatogenesis vs. Oogenesis

    • The key difference is that oogenesis produces one mature ovum from the parent cell, whereas spermatogenesis produces four mature sperm.

    Trigger for Ovulation

    • Luteinizing Hormone (LH) is the necessary trigger for ovulation.

    Uterine Tubes

    • The infundibulum is the funnel-shaped section of the uterine tube located near the ovary.

    Post-Ovulation Changes

    • Immediately after ovulation, the endometrium enters its secretory phase.
