19. External genitalia
 Labia majora
The venous drainage is extensive and
forms a plexus with numerous
anastomoses. Vulva hematoma
 Vaginal vestibule
Bordered by the labia minora laterally,
by the frenulum labiorum pudendal ( 阴
唇系带 ) posteriorly, by the urethra and
clitoris anteriorly, by the hymenal ring
inferiorly.

20. Internal genitalia

21. Internal genitalia

22. Internal genitalia
 Vagina
1. strong canal of muscle (7.5cm)
extend from the uterus to the vestibule of the external
genitalia. its long axis is almost parallel with that of
the lower part of the sacrum. the anterior wall of the
vagina is 1.5-2cm shorter than the posterior wall.
2. vaginal fornix
the circular cul-de-sac formed around the cervix
4 regions: the anterior fornix, the posterior fornix
and 2 lateral fornices.

23. Internal genitalia

epithelium)

periodically

abdominal aorta, (left: left renal
artery).
2) Turn over the common iliac
artery and ureter,descend into
the pelvis. Enter into ovary
through the mesovarium
