urogenital diaphragm การใช้

The lower third is the perineal body; it may be described as containing the perineal body, pelvic diaphragm and urogenital diaphragm.
The term " urogenital diaphragm " is often confused with the pelvic diaphragm ( pelvic floor ), which is a true diaphragm supporting many of the pelvic organs.
Between the superior and inferior fascia of the urogenital diaphragm, the female urethra is surrounded by the urethral sphincter . external urethral sphincter is supplied by the pudendal nerve.
The urethra and the vagina, though part of the pouch, are usually said to be passing through the urogenital diaphragm, rather than part of the diaphragm itself.
Below, the obturator fascia is attached to the falciform process of the sacrotuberous ligament and to the pubic arch, where it becomes continuous with the superior fascia of the urogenital diaphragm.
