The endopelvic fascia is a confluent suspensory apparatus of the female pelvic organs. The endopelvic fascia has the shape of a semifrontally oriented septum, which surrounds the vagina and part of the uterine cervix and divides the pelvic floor into the anterior and posterior compartments.
Pelvic fascia extends to cover the organs within the pelvis. It is attached to the fascia that runs along the pelvic floor along the tendinous arch. The fascia which covers pelvic organs can be divided according to the organs that are covered: The front is known as the “vesical layer”.
Likewise, what muscles support the uterus? The uterus is primarily supported by the pelvic diaphragm, perineal body, and urogenital diaphragm. Secondarily, it is supported by ligaments, including the peritoneal ligament and the broad ligament of uterus.
Beside above, what is Denonvilliers fascia?
The rectoprostatic fascia (Denonvilliers‘ fascia) is a membranous partition at the lowest part of the rectovesical pouch. It separates the prostate and urinary bladder from the rectum. It consists of a single fibromuscular structure with several layers that are fused together and covering the seminal vesicles.
What is perineal body?
The perineal body (or central tendon of perineum) is a pyramidal fibromuscular mass in the middle line of the perineum at the junction between the urogenital triangle and the anal triangle. It is found in both males and females.
What two muscles form the pelvic diaphragm?
On each side, the pelvic diaphragm is formed by two most unequal muscles, the small coccygeus muscle behind, and the much larger and more important levator ani muscle in front. Here’s the coccygeus muscle. It runs from the ischial spine, to the edge of the lower sacrum and coccyx.
What is the fascia?
A fascia (/ˈfæ?(i)?/; plural fasciae /ˈfæ?ii/; adjective fascial; from Latin: “band”) is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs.
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 muscles support pelvic viscera?
What are the 4 diaphragms?
There are 4 major diaphragms in the body: the cranial base, thoracic inlet, respiratory diaphragm, and pelvic floor. They occurred at the junctions where the regions of the vertebrae change function. Each diaphragm is unique, stretches from the front of the body, to the back.
What Innervates the pelvic diaphragm?
The puborectalis muscle is now included in the levator ani muscle group and the term “Levator ani” is used synonymously with pelvic diaphragm muscles. Branches from the sacral nerve roots of S2, S3 and S4 innervate the pelvic floor muscles.
Where do pelvic floor muscles attach?
Pelvic Diaphragm The levator ani and coccygeus muscles that are attached to the inner surface of the minor pelvis form the muscular floor of the pelvis. The thin lateral part of the levator ani is the iliococcygeus muscle, which arises from the arcus tendineus of the levator ani to the ischial spine.
What is 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.
Where is the Mesorectum?
Mesorectum: The mesentery of the rectum, i.e., mesorectum, is the perirectal fatty lymphovascular tissue extending the length of the rectum. The mesorectum encases the rectum as a thick cushion mainly posteriorly and laterally.
What is renal fascia and what is its function?
Holds kidney within abdominal cavity and protects from trauma. The most superficial layer, the renal fascia is made out of what tissue subtype and its function is: dense irregular connective tissue. Anchors kidney to surrounding structures and abdominal wall.
What is the seminal colliculus?
The seminal colliculus (Latin colliculus seminalis), or verumontanum, of the prostatic urethra is a landmark near the entrance of the ejaculatory ducts (on both sides, corresponding vas deferens and seminal vesicle feed into corresponding ejaculatory duct).
What is the space of retzius?
The retropubic space (also known as the prevesical space or cave of Retzius) is an extraperitoneal space located posterior to the pubic symphysis and anterior to the urinary bladder. It is separated from the anterior abdominal wall by the transversalis fascia and extends to the level of the umbilicus.
Which side is female 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.
What ligament holds the uterus in place?
