Sex and Repro Health in Sexology

  1. What organs are part of the Female Repro system?
    • ovaries
    • uterine (fallopian) tubes
    • uterus
    • vagina
    • vulva
    • mammary glands
  2. What is the function of the ovaries?
    • produce secondary oocytes (eggs) and 4 Hormones:
    • Progesterone
    • Oestrogens
    • Inhibin
    • Relaxin
  3. What are ovaries?
    Female gonads on either side of the uterus
  4. What are Gametes?
    secondary oocytes that develop into mature eggs after fertilisation
  5. What are the 4 hormones?
    • Progesterone
    • oestrogen
    • inhibin
    • relaxin
  6. What is homologous?
    When the ovaries arise from the same embryonic gonadal tissue as the testes during embryonic development
  7. How many chromosomes in a haploid?
    23
  8. How many chromosomes in a diploid?
    46
  9. What is oogenesis?
    Formations of gametes (ovum) in the ovaries
  10. What is mitosis?
    The way cells replicate completely
  11. What is zygote?
    when the nuclei of the sperm cell and the ovum unite
  12. What is the Uterus?
    • The host for the developing fetus
    • produces vaginal ad uterine secretions
    • passes the sperm though the fallopian tubes
  13. What are Hormones?
    chemical messengers produced and secreted by organs. They travel via the blood and influence their target tissue.
  14. What are the three phases of the menstrual cycle?
    • 1. The follicular phase.
    • 2. Th ovulatory phase.
    • 3 The Luteal phase.
  15. How do the hormones controls the menstrual cycle?
    Oestrogen causes the uterine lining to grow in preparation for a fertilised egg.

    Progesterone further matures the liniing so it is in the secretory phase where it is ready to interact with the blastocyst should fertilisation happen.
  16. What is the blastocyst?
    structure fromed in the early development of mammals. It possesses an inner cell mass (ICM) which forms the embryo.
  17. What is an embryo?
    multicellular diploid eukaryote
  18. What is the endometrium?
    inner mucous membrane of the uterus
  19. What is a Morula?
    early stage embryo consist of cells in a solid ball contained within the zona pellucida
  20. What is the endocrine gland?
    a ductless gland that secretes a hormone into the blood stream.
  21. What is fertilisation?
    The fusion of two gametes to produce a zygote during sex repro
  22. What is Gametogenesis?
    Formation of gametes by meiosis - either spermatogenesis or oogenisis
  23. What is LH (Luteinising Hormone)?
    a hormone released from the pituitary gland which stimulates the ovarian follicle to ovulate.

    It also stimulates the testes to produce testosterone.
  24. What is the Zygote?
    the fertilised ovum - when the sperm and the ovum fuse
  25. What is the function of the vagina?
    receive the penis during intercourse.

    passageway for childbirth.
  26. What is the function of the uterine tubes?
    transport of an ovum (egg) to the uterus where fertilisation will occur.
  27. What is an oogonium?
    a small diploid cell
  28. How do Oogonia increase in numbers?
    through a process known as mitotic cell division. Meiosis is unique to germ cells. It only occurs in young egg and sperm cells.
  29. How many chromosomes does an oogonium have in its nucleus?
    they have two (2n) complete sets of chromosomes. In the human cell, this is 23 pairs or a total of 46.
  30. What is the corpus luteum?
    It s a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A.

    It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation.
  31. What are the components of the Vulva?
    • Mons Pubis
    • Labia Majora
    • Labia Minora
    • Clitorus
  32. After birth, ooginium cells remain in arrested development until what age?
    puberty
  33. How many days after fertilisation does implantation occur?
    8 days
  34. How long is the developing individual referred to as an embryo?
    8 weeks
  35. How long is the developing individual referred to as a foetus?
    8w to birth
  36. When and where is the hormone prolactin produced?
    Pituitary gland after birth
