The urogenital triangle is the anterior part of the perineum. In female mammals, it contains the vulva, while in male mammals, it contains the penis and scrotum.
Structure
[edit]The urogenital triangle is the area bound by a triangle with one vertex at the pubic symphysis and the two other vertices at the iliac tuberosities of the pelvic bone.
Components
[edit]As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include:[1]
- Posterior scrotal nerves / posterior labial nerves
- Urethra
- Vagina
- Bulbourethral gland / Bartholin's gland
- Muscles
- Penile crura / clitoral crura
- Bulb of penis / vestibular bulbs
- Urogenital diaphragm
- Muscular perineal body
- Superficial and deep perineal pouch
- Blood vessels and lymphatics
