Hi viewers:

Today we discuss about the internal and external structure of female reproductive organ of Homo

Female Reproductive Organs:

External Genital Organs
1.  Vulva
2.  Urethral opening

Internal Genital Organs
1.  A pair of ovary  2.  Fallopian tubes  3.  Uterus  4.  Cervix  5.  Vagina  6. Bartholin’s gland

 

  1. Ovary: The two ovaries are solid ovoid or bean shaped structures approximately 3.5 cm in length and 1.5-205 cm in thickness.  Each ovary weighs 4-8 gm.  They are attached to the back of the broad ligament by mesovarium, one on either side of the uterus and near the free end of the fallopian tube.  Each is suspended in the body cavity by an ovarian ligament through blood vessels, lymphatics and nerves enter into the ovary.  The ovaries are the paired mixed sex glands and in function produce ovum and sex hormones.

 

  1. Vulva: It comprises clitoris (glans), labia mazora, labia minora, vaginal orifice, hymen and vestibulea.  Clitoris
    An erectile body, rarely exceeding 2 cm in length, situated at the most anterior portion of the vulva and projecting between the branched extremities of the labia minora and is the homologue of the penis in the male, except that it is not perforated by the urethra and does not possess a corpus spongiosum.b.  Labia mazora
    Two rounded folds of integument forming the lateral boundaries of the vaginal orifice.c.  Labia minora
    Two narrow longitudinal folds of mucous membrane enclosed in the cleft within the labia majora.d. Hymen
    A thin crescentic or annular membranous fold partly occluding the vaginal external orifice in the virgin.

    e.  Vestibule
    The space behind the clitoris between the labia minora, containing the openings of the vagina, urethra, and ducts of the greater vestibular glands.

    f.  Vaginal orifice
    The slit of the vagina where penis is introduced

 

  1. Fallopian tubes: One of the tubes leading on either side from the fundus of the uterus to the upper or outer

extremity of the ovary; it consists of infundibulum, ampulla, isthmus, and uterine parts.

  1. Uterus
    The hollow muscular organ in which the impregnated ovum is developed into the child; it is about

7.5 cm in length in the nonpregnant woman, and consists of a main portion (corpus or body) with an

elongated lower part (cervix or neck), at the extremity of which is the opening (os or mouth). The

upper rounded portion of the uterus, opposite the os, is the fundus, at each extremity of which is the

horn marking the part where the uterine (fallopian) tube joins the uterus and through which the ovum

reaches the uterine cavity after leaving the ovary.

  1. Cervix
    The lower part of the uterus extending from the isthmus of the uterus into the vagina. It is dividedinto supravaginal and vaginal parts by its passage through the vaginal wall.
  1. Vagina: The genital canal in the female, extending from the uterus to the vulva
  2. Bartholin’s gland: One of two mucoid-secreting tubuloalveolar glands on either side of the lower part of the

vagina, the equivalent of the bulbourethral glands in the male.
