Now, dissect the region of the urogenital triangle. As this is done, the structures located in the superficial perineal pouch will be identified. The superficial perineal pouch lies between the Colles' fascia and inferior fascia of the urogenital diaphragm. Anteriorly, it extends to the potential space between the superficial fascia and the anterior abdominal muscles. Posteriorly, the superficial perineal pouch is bounded by the superficial transverse perineal muscles and the perineal body. Laterally the pouch extends to the ischiopubic rami. Remove the remaining superficial fascia deep to the skin of the labia majora and identify the superficial branches of the internal pudendal vessels and cutaneous branches of the superficial perineal nerves. In the female,
these are called the posterior labial nerves and vessels . Trace the nerves to their origin from the superficial branch of the perineal nerve (Figure 41.4).
