    • ANATOMI REPRODUKSI WANITA

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

    • Some general physiologic responses
      • Blood pressure: elevation of 30-80 mm Hg
      • Heart rate: elevation to 110-180/min
      • Vasocongestion (both skin and deep tissues)
      • Respiration: elevation to over 40/min
      • Anal sphincter contractions
      • Muscle contractions (esp. hands and feet)
    • Orgasm
