[edit] Structure
The urogenital triangle is the area bound by a triangle with one vertex at the pubic symphysis and the two other vertices at the ischiopubic rami of the pelvic bone.
[edit] Components
As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include:
- Posterior scrotal nerves / Posterior labial nerves
- Urethra
- Bulbourethral gland / Bartholin's gland
- Muscles
- Crus penis / Clitoral crura
- Bulb of penis / vestibular bulb
