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

3. Labia minora (labia minora pudendi)
4. Clitoris – the female erectile organ
5. 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)
