The lower third is the perineal body; it may be described as containing the perineal body, pelvic diaphragm and urogenital diaphragm.
2.
The term " urogenital diaphragm " is often confused with the pelvic diaphragm ( pelvic floor ), which is a true diaphragm supporting many of the pelvic organs.
3.
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.
4.
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.
5.
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.
6.
The term " diaphragm " in anatomy can refer to other flat structures such as the urogenital diaphragm or pelvic diaphragm, but " the diaphragm " generally refers to the thoracic diaphragm.
7.
In the male, it runs forward and medially, pierces the inferior fascia of the urogenital diaphragm and enters the corpus cavernosum urethr? in which it is continued forward to the glans penis.
8.
Commencing below the inferior fascia of the urogenital diaphragm it passes forward and upward to the front of the pubic symphysis; and then, in the flaccid condition of the penis, it bends downward and forward.
9.
It extends downward and forward, with a slight anterior concavity, between the apex of the prostate and the bulb of the urethra, perforating the urogenital diaphragm about 2.5 cm below and behind the pubic symphysis.
10.
The ridges are continuous with similar ones on the inferior ramus of the pubis : to the outer is attached the deep layer of the superficial perineal fascia ( fascia of Colles ), and to the inner the inferior fascia of the urogenital diaphragm.
