Internal Organs+Glands · 93. Vagina. Female external genitalia.

Covers the female external genitalia, the vulva, starting with the vestibule and its openings and glands, including the vaginal orifice, Bartholin's glands and the external urethral orifice. It then moves through the labia majora and minora, the commissures, the clitoris with its crura, body, glans, prepuce and frenulum, and the bulb of the vestibule. The note closes with the arterial, venous and lymphatic supply and the sensory and autonomic innervation, shown in three pictures.

EXTERNAL GENITALIA

  • Also called (Vulva).
  • Includes all the visible external genital organs in the perineum.

External structure:

  1. 1 Vestibule (vestibulum vaginae)
  2. 1.1 Vaginal orifice (ostium vaginae) – the external opening of the vagina
  3. 1.2 Greater vestibular gland / Bartholin’s gland (glandula vestibularis major Bartholini)
  • – a paired mucous gland embedded in the perineal membrane
  • – opens into the posterior part of the vestibule
  1. 1.3 Lesser vestibular glands (glandulae vestibulares minores)
  2. 1.4 External urethral orifice (ostium urethrae externum)
  • – the external opening of the female urethra
  1. 2 Labia majora (labia majora pudendi)
  2. 2.1 Anterior commissure (commissura labiorum anterior)
  • – the anterior connection of the two labia majora
  • – is located ventral to the prepuce of the clitoris
  1. 2.2 Posterior commissure (commissura labiorum posterior)
  • – the posterior connection of the two labia majora, behind the vestibule
  1. 3 Labia minora (labia minora pudendi)
  2. 4 Clitoris – the female erectile organ
  3. 4.1 Crura of clitoris (crura clitoridis)
  • – paired bodies of erectile tissue attached to the phallic crest of the inferior pubic ramus
  • – meet in the midline at the body of the clitoris
  1. 4.2 Body of clitoris (corpus clitoridis) – is formed by fusion of the crura of the clitoris
  2. 4.3 Glans of clitoris (glans clitoridis) – the terminal part of the clitoris
  3. 4.4 Prepuce of clitoris (preputium clitoridis) – is located on the ventral aspect of the clitoris
  4. 4.5 Frenulum of clitoris (frenulum clitoridis)
  5. 5 Bulb of vestibule (bulbus vestibuli) – a pair of erectile bodies encircling the vestibule
  • – ventrally connected at the commissure of the bulbs (commissura bulborum)
