Urogenital triangle

The urogenital triangle is the anterior part of the perineum. In female mammals, it contains the vagina and associated parts of the external genitalia.

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 ischial tuberosities of the pelvic bone.

  • Posterior scrotal nerves / Posterior labial nerves
