FEMALE REPRODUCTIVE ANATOMY

EXTERNAL GENITALIA:

  • Mons Pubis - a pad of adipose tissue over symphysis pubis, covered by curly hair; for protection against trauma.
  • Glans clitoris - a small rounded organ (approximately 1-2 cm) of erectile tissue at the forward junction of the labia minora, covered by prepuce.
  • Urethra meatus - urethral opening.
  • Labia majora - two folds of adipose tissue covered by loose connective tissue and epithelium, lateral to labia majora; serves as protection for external genitalia.
  • Labia minora - posterior to mons veneris are two folds of connective tissues.
  • Hymen - tough but elastic semicircle of tissue that covers the opening to the vagina in childhood.
  • Fourchette - the ridge of tissue formed by the posterior joining of the two labia minora and labia majora.
  • Perineum - perineal muscles posterior to the fourchette; stretchable during childbirth.

INTERNAL GENITALIA:

  • Vestibule - a flattened, smooth surface inside the labia.
  • Bartholin's gland - vulvovaginal gland; just lateral to the vaginal opening of both sides; lubricates the external vagina during coitus.
  • Skenes gland or para urethral gland - located just lateral to the urinary meatus on both sides; lubricate the external genitalia during coitus.
  • Vagina - muscular organ that extends from the vulva to the uterine cervix; approx. 6-7 cm long.
  • Cervix - the lowest portion of uterus; about 2-5 cm long; cavity is termed cervical canal, jucntion of the canal at isthmus is internal cervical os.
  • Uterus - about 5-7 cm long, 5cm wide and 2.5 cm deep in it's widest upper part; receives ova, provides a place for implantation and nourishment during fetal growth, furnishes protection to a growing fetus, expel it from the woman's body; Three divisions are:
  • a. the body or corpus
  • b. the isthmus
  • c. the cervix
  • Fallopian tubes - 8-14 cm muscular tubes that extend laterally from the cornua of the uterus; convey ova from ovaries to uterus; Segments are: interstitial, isthmus, ampulla and infundibulum.
  • Ovaries - function is to produce, mature and discharge egg cells; Consist of ovarian cortex, which is responsible to maturation of ova and production of large amount of estrogen and progesterone; and ovarian medulla contains connective tissue and the blood supply to the ovary.
