Study the vulva in the region of the urogenital triangle . Identify the mons pubis, an elevated region located anterior and superior to the pubic symphysis. It is caused by a thick deposit of fat beneath the overlying skin.Next identify the labia majora , the hair-bearing folds of skin which extend posteriorly from the mons pubis. The point at which the labia majora meet posteriorly is called the posterior labial commissure.
Medial to the labia majora, identify the thinner folds of skin, the labia minora , which lie just external to the vestibule of the vagina [space located below the probe]. Confirm the fact that the labia minora are not covered by hair.
