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.
Vestibule/vulvar opening: In humans, other great apes, and some rodents, the vestibule is a flat and short external space that contains separate urethral and vaginal openings. In most other placentals, the urethra and vagina join as an internal vestibule ( urogenital sinus ), hence both urine and offspring exit through an orifice called the ...
The two Skene's ducts lead from the Skene's glands to the vulvar vestibule, to the left and right of the urethral opening, from which they are structurally capable of secreting fluid. [2] [3] Although there remains debate about the function of the Skene's glands, one purpose is to secrete a fluid that helps lubricate the urethral opening. [2] [3]
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 ...
In human anatomy, and in mammals in general, the mons pubis or pubic mound (also known simply as the mons / m ɒ n z /, and known specifically in females as the mons Venus or mons veneris) [1] [2] is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones.
They enclose and protect the vulvar vestibule, urethra and vagina. The upper portion of each of the labia minora splits to join both the clitoral glans , and the clitoral hood . The labia minora meet posteriorly at the frenulum of the labia minora (also known as the fourchette), which is a fold of skin below the vaginal orifice.
The urethra of an adult human female is 3-4 cm long. [4] The female urethra is located between the bladder neck to the external urethral orifice and is behind the symphysis pubis. [4] The urethral wall is composed of an inner epithelial lining, a sub-mucosa layer containing vascular supply, a thin fascial layer, and two layers of smooth muscle. [4]
