Perineal membrane
The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane....

Structure
The deep perineal pouch is bordered inferiorly by the perineal membrane, also known as the inferior fascia of the urogenital diaphragm. It is bordered superiorly by the superior fascia of the urogenital diaphragm. The deep pouch is now described as the region between the perineal membrane and pelvic diaphragm.Contents

In human anatomy, the pelvis is the lower part of the trunk, between the abdomen and the lower limbs .The pelvis includes several structures:...

Superior fascia of the urogenital diaphragm
The superior fascia of the urogenital diaphragm is continuous with the obturator fascia and stretches across the pubic arch.If the obturator fascia be traced medially after leaving the Obturator internus muscle, it will be found attached by some of its deeper or anterior fibers to the inner margin...
