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
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
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
Vagina
Bulbourethral gland / Bartholin's gland
Muscles
Superficial transverse perineal muscle
Ischiocavernosus muscle
Bulbospongiosus muscle
Penile crura / clitoral crura
Bulb of penis / vestibular bulbs
Urogenital diaphragm
Muscular perineal body
Superficial and deep perineal pouch
Blood vessels and lymphatics
