Structures opening in the vulval vestibule are the urethra (urinary meatus), vagina, Bartholin's glands, and Skene's glands. [1]The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) [2] behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins.
The area between the labia minora where the vaginal introitus and the urinary meatus (openings of the vagina and urethra respectively) are located is the vestibule. The meatus is below the clitoris and atop the introitus. The introitus is sometimes partly covered by a membrane called the hymen.
The urethra (pl.: urethras or urethrae) is the tube that connects the urinary bladder to the urinary meatus, [1] [2] through which placental mammals urinate and ejaculate. [3] In non-mammalian vertebrates , the urethra also transports semen but is separate from the urinary tract.
Urinary meatus: the opening of the urethra for urine to pass through. Vaginal opening: entrance to the vagina. Hymen: connective tissue that covers the vaginal opening. Vestibular gland openings: two pairs of openings in the vulval vestibule for the Bartholin's and Skene's glands.
The term vagina is from Latin vāgīna, meaning "sheath" or "scabbard". [1] The vagina may also be referred to as the birth canal in the context of pregnancy and childbirth. [2] [3] Although by its dictionary and anatomical definitions, the term vagina refers exclusively to the specific internal structure, it is colloquially used to refer to the vulva or to both the vagina and vulva.

The urinary meatus [a] (/ m iː ˈ eɪ t ə s /, mee-AY-təs; pl.: meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees ...
