female-reproductive-organs

  1. 1. ANATOMI REPRODUKSI WANITA <ul><li>ALIA ANDRIANY </li></ul>S2 BIOMEDIK FISIOLOGI PROGRAM PASCASARJANA UNHAS
  2. 2. Female reproductive system <ul><li>The female reproductive organs, or genitalia, are divided into external and internal organs. </li></ul><ul><li>External genitalia (vulva) </li></ul><ul><li>The external genitalia are known collectively as the vulva </li></ul><ul><li>It consists of the mons pubic, labia majora and labia minora, the clitoris, the vaginal orifice, the vestibule, and breasts </li></ul>
  3. 3. Labia majora <ul><li>These are the two large folds forming the boundary of the vulva. </li></ul><ul><li>They are composed of skin, fibrous tissue and fat and contain large numbers of sebaceous glands. </li></ul><ul><li>Anteriorly the folds join in front of the symphysis pubis, and posteriorly they merge with the skin of the perineum. </li></ul><ul><li>At puberty, hair grows on the mons pubis and on the lateral surfaces of the labia majora . </li></ul>
  4. 4. Labia minora <ul><li>These are two smaller folds of skin between the labia majora, containing numerous sebaceous glands. </li></ul><ul><li>The cleft between the labia minora is the vestibul e . </li></ul><ul><ul><li>covered with smooth, hairless skin </li></ul></ul>
  5. 5. Clitoris <ul><li>The clitoris corresponds to the penis in the male and contains sensory nerve endings and erectile tissue. </li></ul>
  6. 6. Hymen <ul><li>The hymen is a thin layer of mucous membrane that partially occludes the opening of the vagina. </li></ul><ul><li>It is normally incomplete to allow for passage of menstrual flow. </li></ul>
  7. 8. Vestibule & Vestibular glands <ul><li>The vagina, urethra and ducts of the greater vestibular glands open into the vestibule. </li></ul><ul><li>The vestibular glands ( Bartholin's glands ) are situated one on each side near the vaginal opening </li></ul><ul><li>They secrete mucus that keeps the vulva moist. </li></ul>
  8. 9. Perineum <ul><li>The perineum is the area extending from the base of the labia minora to the anal canal. </li></ul><ul><li>It is roughly triangular and consists of connective tissue, muscle and fat. </li></ul><ul><li>An episiotomy is an incision of the perinium used during childbirth for widening the vaginal opening </li></ul>
  9. 10. PERINEUM UNIT 3: FEMALE REPRODUCTIVE SYSTEM
  10. 11. <ul><li>Organs of sexual arousal </li></ul><ul><li>Contain mammary glands </li></ul><ul><li>Each breast contain 15-25 clusters called lobes </li></ul><ul><li>Each lobule is connected by ducts that open into the nipples </li></ul><ul><li>The nipples are made up of erectile tissue </li></ul><ul><li>The pigmented around the nipples are called the areola </li></ul>BREAST
  11. 12. 22-48
  12. 13. Organs of Female Reproductive System <ul><li>Ovaries </li></ul><ul><li>Fallopian tubes </li></ul><ul><li>Uterus </li></ul><ul><li>Vagina </li></ul>
  13. 14. The Ovaries
  14. 15. OVARIES <ul><li>The female gonads or sex glands </li></ul><ul><li>They develop and expel an ovum each month </li></ul><ul><li>A woman is born with approximately 400,000 immature eggs called follicles </li></ul><ul><li>During a lifetime a woman release @ 400 to 500 fully matured eggs for fertilization </li></ul><ul><li>The follicles in the ovaries produce the female sex hormones, progesterone and estrogen </li></ul><ul><li>These hormones prepare the uterus for implantation of the fertilized egg </li></ul>UNIT 3: FEMALE REPRODUCTIVE SYSTEM
  15. 16. Oogenesis <ul><li>OOGENESIS </li></ul><ul><li>Also called ovum production </li></ul><ul><li>Begins before birth </li></ul><ul><li>Accelerates at puberty </li></ul><ul><li>Ends at menopause </li></ul>
  16. 18. VIDEO
  17. 19. <ul><li>Serve as a pathway for the ovum to the uterus </li></ul><ul><li>Are the site of fertilization by the male sperm </li></ul><ul><li>Often referred to as the oviducts or uterine tubes </li></ul><ul><li>Fertilized egg takes approximately 6 to 10 days to travel through the fallopian tube to implant in the uterine lining </li></ul>UTERINE TUBE UNIT 3: FEMALE REPRODUCTIVE SYSTEM
  18. 21. Uterus <ul><li>The uterus is a hollow muscular pear-shaped organ, flattened anteroposteriorly. </li></ul><ul><li>It lies in the pelvic cavity between the urinary bladder and the rectum. </li></ul><ul><li>When the body is upright, the uterus lies in an almost horizontal position. </li></ul><ul><li>It is about 7.5 cm long, 5 cm wide and its walls are about 2.5 cm thick. It weighs from 30 to 40 grams. </li></ul><ul><li>The parts of the uterus are the fundus , body and cervix: </li></ul>
  19. 23. VAGINA <ul><li>The vagina connects the cervix to the external genitals </li></ul><ul><li>It is located between the bladder and rectum </li></ul><ul><li>It functions : </li></ul><ul><li>As a passageway for the menstrual flow </li></ul><ul><li>For uterine secretions to pass down through the introitus </li></ul><ul><li>As the birth canal during labor </li></ul><ul><li>With the help of two Bartholin’s glands becomes lubricated during SI </li></ul>UNIT 3: FEMALE REPRODUCTIVE SYSTEM
  20. 25. Response Sexual Cycle <ul><li>Excitement phase </li></ul><ul><li>Plateau Phase </li></ul><ul><li>Orgasm Phase </li></ul><ul><li>Resolution Phase </li></ul>
