Presentation Transcript

  1. Female Reproductive System - Overview 1. Ovaries 2. DuctSystem • Uterine Tubes • “Fallopian tubes” • Uterus • Vagina 3. ExternalGenitalia 4. MammaryGlands

  2. Ovaries 1. Function • Follicles • Mature oocyte or ovum ovulated • Corpus luteum 2. Structure • Tunica albuginea • Ligaments • Ovarian • Suspensory • Broad • Mesovarium

  3. Uterine Tubes • 1. Function • 2. Structure • Fimbriae and Infundibulum • Ampulla • Fertilization • Isthmus • Mesosalpinx and Mesovarium

  4. Uterus 1. Function 2. Structure • Body and Fundus • Cervix and cervical canal • Uterine Wall • Perimetrium • Myometrium • Endometrium 3. EndometriumStratum • Functionalis • Basalis 4. BloodSupply

  5. Vagina 1. Function 2. Structure • Wall • Mucosa • Vaginal orifice • Hymen • Fornix

  6. External Genitalia 1. Function 2. Vulva • Mons pubis; labia; clitoris; vestibule structures 3. Labia • Majora and minora 4. Vestibule • Glands 5. Clitoris • Glans clitoris • Prepuce • Body 6. Perineum

  7. Mammary Glands 1. Function 2. Structure • Areola • Nipple • Lobes • Suspensory ligaments • Lobules and alveoli • Lactiferous ducts and sinus 3. BreastCancer

  8. Physiology – Oogenesis 1. Function 2. Process • Oogonia • Primordial follicles • Primary oocytes • Secondary oocytes • Ovum • Polar bodies 3. Interestingfacts • Survival of oocytes from birth • Puberty and oocytes • Female Reproductive life

  9. Ovarian Cycle 1. Function 2. FollicularPhase • Primordial follicle maturation • Primary to secondary follicle • Secondary follicle matures • Formation of a vesicular follicle • Ovulation 3. LutealPhase • Corpus hemorrhagicum • Corpus luteum • Corpus albicans

  10. Ovarian Cycle

  11. Control of the Ovarian Cycle-Hormonal Interaction 1. GnRH stimulates FSH and LH 2. FSH and LH stimulate follicle growth • Granulosa cells and FSH • LH and Thecal cells • Estrogen 3. Negative Feedback • Inhibit FSH and LH release 4. Positive Feedback • High estrogen levels cause axis to increase production 5. LH Surge • High estrogen levels and LH 6. Ovulation • LH surge

  12. Ovarian Cycle Control

  13. Uterine – Menstrual Cycle 1. Function 2. MenstrualPhase (1-5) • Menstruation • Endometrium 3. ProliferativePhase (6-14) • Rebuilding of endometrium • Ovulation 4. SecretoryPhase (15-28) • Preparation of implantation of embryo • Corpus Luteum (failure)

  14. Summary of Estrogen

  15. Summary of Progesterone

  16. Effects of Testosterone
