The urogenital diaphragm, also called the triangular ligament, is a strong, muscular membrane that occupies the area between the symphysis pubis and ischial tuberosities and stretches across the triangular anterior portion of the pelvic outlet. The urogenital diaphragm is external and inferior to the pelvic diaphragm.

Simply so, what is urogenital diaphragm?

Medical Definition of urogenital diaphragm : a double layer of pelvic fascia with its included muscle that is situated between the ischial and pubic rami, supports the prostate in the male, is traversed by the vagina in the female, gives passage to the membranous part of the urethra, and encloses the sphincter urethrae.

Beside above, what forms the urogenital diaphragm? The urogenital diaphragm consists of the deep transverse perineal muscle with the superior and inferior fascia. It is intimately associated with the compressor urethrae and the urethrovaginal sphincter muscle of the distal urethra with the urethra and its surrounding connective tissue.

Likewise, what is the pelvic diaphragm?

The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. It separates the pelvic cavity above from the perineal region below.

What passes through the pelvic diaphragm?

The levator ani and coccygeus muscles are covered over by this dense layer of pelvic fascia, which completes the pelvic diaphragm on the inside. The pelvic diaphragm supports the pelvic organs and closes off the pelvic outlet, while allowing passage for the rectum, vagina and urethra.

What is in the urogenital triangle?

Urogenital Triangle. The urogenital triangle is the anterior half of the perineum. It is bounded by the pubic symphysis, ischiopubic rami, and a theorectical line between the two ischial tuberosities. The triangle is associated with the structures of the urogenital system – the external genitalia and urethra.

What are the perineal muscles?

  • The transverse perineal muscles (transversus perinei) are the superficial and the deep transverse perineal muscles.
  • The superficial transverse perineal muscle (transversus superficialis perinei) is a narrow muscular slip, which passes more or less transversely across the perineal space in front of the anus.

What is perineal membrane?

Where is the pelvic diaphragm?

The pelvic diaphragm is a wide but thin muscular layer of tissue that forms the inferior border of the abdominopelvic cavity. Composed of a broad, funnel-shaped sling of fascia and muscle, it extends from the symphysis pubis to the coccyx and from one lateral sidewall to the other.

What are the female pelvic organs?

Anatomy of Female Pelvic Area
  • Endometrium. The lining of the uterus.
  • Uterus. Also called the womb, the uterus is a hollow, pear-shaped organ located in a woman's lower abdomen, between the bladder and the rectum.

Is the bladder in the pelvic cavity?
