urogenital diaphragm

It is bordered superiorly by the superior fascia of the urogenital diaphragm.

The urogenital diaphragm is reinforced posteriorly by the superficial transverse perineal.

"Urogenital diaphragm"

The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane.

The uterus is primarily supported by the pelvic diaphragm, perineal body and the urogenital diaphragm.

Approximately 10% of patients with cystectomy for bladder cancer can be expected to have or develop urethral cancer distal to the urogenital diaphragm.

Between the superior and inferior fascia of the urogenital diaphragm, the female urethra is surrounded by the Sphincter urethae.

They arise from the lower part of the pubic symphysis, and from the superior fascia of the urogenital diaphragm.

If the inferior fascia of the urogenital diaphragm is detached on either side, the following structures will be seen between it and the superior fascia:

The superior fascia of the urogenital diaphragm is continuous with the obturator fascia and stretches across the pubic arch.

The deep perineal pouch is bordered inferiorly by the perineal membrane, also known as the inferior fascia of the urogenital diaphragm.

The term "urogenital diaphragm" is often confused with the pelvic floor, which is a true diaphragm supporting many of the pelvic organs.

Posteriorly, it curves around the Transversi perinæi superficiales to join the lower margin of the inferior fascia of the urogenital diaphragm.

Sustentacular part supports the pelvic organs and comprises the larger pelvic diaphragm in the back and the smaller urogenital diaphragm in the front.

The urogenital diaphragm consists mainly of the deep transverse perineal which arises from the inferior ischial and pubic rami and extends to the urogential hiatus.

Behind, it is expanded to form the urethral bulb, and lies in apposition with the inferior fascia of the urogenital diaphragm, from which it receives a fibrous investment.

A 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.

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.

It passes medialward, pierces the inferior fascia of the urogenital diaphragm and gives off branches which ramify in the bulb of the urethra and in the posterior part of the corpus spongiosum.

The external sphincter muscle of urethra (or sphincter urethrae membranaceae) surrounds the whole length of the membranous portion of the urethra, and is enclosed in the fasciæ of the urogenital diaphragm.
