Short Note

Answer in one sentence.

Enlist the external genital organs in the female.



The external genital organs of female include parts external to the vagina, collectively called vulva (covering or wrapping), or pudendum. They include the following parts:

  1. Vestibule:
    It is a median vertical depression of the vulva enclosing the urethral and vaginal opening.
  2. Labia minora:
    These are another pair of thin folds inner to the labia majora with which they merge posteriorly to form the fourchette (frenulum), while towards the anterior end they converge into a hood-like covering around the clitoris.
  3. Clitoris:
    A small conical and sensitive projection lying at the anterior end of labia minora. It has a pair of erectile tissue i.e. corpora cavernosa which is homologous to the penis.
  4. Labia majora:
    These are a pair of fleshy folds of skin forming the boundary of the vulva. They are homologous to the scrotum. They surround and protect the other parts of the external genitalia and enclose the urethral and vaginal openings in the vestibule.
  5. Mons pubis:
    It is a fleshy elevation above the labia majora. The Mons pubis and outer part of labia majora show pubic hair.
