  1. 1. 杨冬梓 Dongzi Yang Memorial Hospital of Sun Yat-Sen University 中山大学 附属孙逸仙纪念医院妇产科 Welcome to the course of Obstetrics & Gynecology
  2. 2. Chapter 1-2 Female reproductive system 女性生殖系统 Obstetrics & Gynecology
  3. 3. Female reproductive system  Organization (Anatomy)  Functions ( Physiology )  Visualize the anatomical structure of the female reproductive system.  Describe the hormones that regulate the female reproductive system.  Explain the sequence of events during the menstrual cycle. Contents After learning these two chapters, you should be able to :
  4. 4. Chapter 1: Anatomy of the female reproductive system  Adjacent organs  The blood ,nerve, and lymphatic supplies to the pelvic structures (self-study)  The pelvic structures  External and internal genitalia Be familiar with Comprehend
  5. 5. Female reproductive system The Pelvis  Structures  Dividing line  Types External genital organs Internal genital organs  Vagina  Uterus  Fallopian tubes (oviducts)  Ovaries
  6. 6. Anterior view Posterior view Bony pelvis
  7. 7. 《 supper mom’s body 》
  8. 8. Bony pelvis: Structures ilium sacrum pubis coccyx ischium 左右耻骨 Os pubis 左右坐骨 Os ischium 左右髂骨 Os ilium 左右 髋骨 Os coxae (Innominate bone) 4 or 5 caudal or coccygeal vertebrae 尾骨 Os coccyx 5 or 6 sacral vertebrae 骶骨 Os sacrum

  10. 10. Bony pelvis: The Ligaments 骶结节韧带 Lig. sacrotuberale attached to the ilium,sacral vertebrae and the ischial tuberosity 骶棘韧带 Lig. sacrospinale extending from the sacrum and coccyx to the spine of the ischium
  11. 11. Bony pelvis: The greater pelvis (false pelvis) The lesser pelvis (true pelvis) subpubic angle (pubic arch)
  12. 12. <ul><li> O utline : connet the promontory of the sacrum with </li></ul><ul><li>the superior margin of the pubis (耻骨联合上 </li></ul><ul><li>缘、 髂耻缘及骶岬上缘的连线) </li></ul><ul><li> I nlet </li></ul><ul><li> O utlet </li></ul><ul><li> Female pelvic cavity: broader and shallower </li></ul>Bony pelvis: Planes
  13. 13. The pelvic inlet 13-14cm 12.5cm 11.5cm Diameters of the pelvic inlet Transverse diameter Oblique diameter The anteroposterior diameter
  14. 14. The pelvic outlet 10-12cm 9cm The diameters of the pelvic outlet The anteroposterior diameter The transverse diameter of the outlet
  15. 15. Types of pelvis Gynecoid Android Anthropoid platypelloid The female pelvic inlet is oval; The pelvic cavity is broader and shallower, The bony wall of the pelvic canal are more vertical Subpubic angle is broader in the female pelvis.
