Unfortunately, the term is still in common use despite the fact that such a discrete border of the sac probably does not exist.

Nevertheless, the urogenital diaphram usually includes:

  1. sphincter urethrae muscle (external urethral muscle )
  2. deep transverse perineal muscle
  3. superficial transverse perineal muscle
  4. perineal membrane
The urogenital diaphragm is often confused with the pelvic floor, which is a true diaphragm supporting many of the pelvic organs.
