Anatomy & Physiology Reproductive #1


Which is an internal female reproductive organ?


  1. Labia minora
    • Rationale:

      The labia minora is an external, not internal, female reproductive organ. It is described as the labia that forms the inner and smaller perimeter that surrounds the opening of the vagina.

  2. Perineal body
    • Rationale:

      The perineal body (i.e., central tendon of the perineum) is a pyramidal fibromuscular mass that is considered an external, not internal, reproductive organ for both females and males. It is located the middle line of the perineum at the junction between the anal triangle and the urogenital triangle.

  3. Fallopian tube
    • Rationale:

      The fallopian tubes are an internal female reproductive organ. The fallopian tube is where fertilization of the ovum occurs.

  4. Vaginal vestibule
    • Rationale:

      A vestibule is a cavity or space at the entrance to a vessel, tube, channel, or canal. The vaginal vestibule (i.e., vaginal opening) is an external, not internal, female reproductive organ.


The female reproductive system consists of external and internal organs.


Learning Outcomes

The organs of the female reproductive system are classified as either internal organs or external organs. The internal organs include the fallopian tubes, ovaries, uterus, and the vagina. The external organs include the clitoris, labia majora, labia minora, mons pubis, perineal body, urethral meatus, and vaginal vestibule.

Test Taking Tip

Eliminate wrong answers! Consider each answer choice asking yourself, “Is this an internal female reproductive organ?”
