Vulvar

 

  • Introitus (Vaginal Opening)- the entrance to the vaginal canal.
  • Vulva (Genatalia) - the external portion of the female genitalia. This includes the ‘skin folds’ or ‘lips’ (labia majora/labia minora), the clitoris, the urethral opening, and the vaginal entrance.
  • Mons Pubis – is the adipose tissue lying above the pubic bone of adult females, anterior to the pubic symphysis. The mons pubis forms the anterior portion of the vulva. The size of the mons pubis varies with the general level of hormone and body fat. After puberty it is covered with pubic hair and enlarges.
  • Labia Majora - The labia majora constitute the lateral boundaries of the pudendal cleft, which contains the labia minora, interlabial sulci, clitoral hood, clitoral glans, frenulum clitoridis, the Hart’s Line, and the vulval vestibule, which contains the external openings of the urethra and the vagina.Each labium majus has two surfaces, an outer, pigmented and covered with strong, crisp hairs; and an inner, smooth and beset with large sebaceous follicles.The labia majora are thicker in front, where they form by their meeting the anterior commisure of the labia majora.The labia majora correspond to the scrotum in the male.
  • Labia Minora -The Labia Minora are bilateral mucosal-cutaneous refolds located betweeen the labia majora and vulvar vestibule.while there is a wide range of normal anatomic variants, in general , the labia minora are semicircular with a 3-CM long base and a free edge extending from the clitoris to the posterior commissure.The medial mucosal surface are derived from the primitive urogenital sinus and is shiny and pink.the free edge and the lateral cutaneous surface are derived from the urethra folds and are more deeply pigmented.
  • Clitoris -The clitoris is the human female’s most sensitive erogenous zone and the primary source of female sexual pleasure. In humans, the visible button-like portion is near the front junction of the labia minora (inner lips), above the opening of the urethra. Unlike the penis, the male variant of the clitoris, it usually does not contain the distal portion or opening of the urethra and is therefore not used for urination. The size and shape of the clitoris varies from woman to woman. Generally, it is between 1/8 to 3/8 of an inch in size.
  • Urethral Opening - the small opening just below the clitoris and directly above the vaginal opening. Urine from the bladder passes through this opening. The urethra is the tube that facilitates urine passage from the bladder.
  • Vagina -  is a fibromuscular tubular tract which is a sex organ and has two main functions; sexual intercourse and childbirth. In humans, this passage leads from the opening of the vulva to the uterus (womb), but the vaginal tract ends at the cervix. Unlike men, who have only one genital orifice, women have two, the urethra and the vagina. The vaginal opening is much larger than the urethral opening, and both openings are protected by the labia.The inner mould of the vagina has a foldy texture which can create friction for the penis during intercourse. During arousal, the vagina gets moist to facilitate the entrance of the penis.The vagina is the tubular structure that connects the uterus and cervix to the outside of the body. The vagina passes menstrual blood, permits sexual intercourse, and is the passageway during child birth.
