transversalis fascia การใช้

• The peritoneum lies deep to the posterior layer of transversalis fascia and is very adherent to it.
• The separation of transversalis fascia and peritoneum contains loose fatty tissue allowing for the filling of the bladder.
• Medially, however, the peritoneum reflects on the roof of the bladder and runs sharply dorsally, away from the deep layer of transversalis fascia.
• Medial to the vessels the iliac fascia is attached to the pectineal line behind the conjoint tendon, where it is again continuous with the transversalis fascia.
• It ascends obliquely and laterally, posterior to the inguinal ligament, contained in a fibrous sheath formed by the junction of the transversalis fascia and iliac fascia.
• It then pierces the transversalis fascia and passes medially along the inner lip of the crest of the ilium to a point where it perforates the transversus abdominis muscle.
• On the anterior wall of the abdomen, except in the pubic region, and on the lateral wall above the iliac crest, it is scanty, and here the transversalis fascia is more closely connected with the peritoneum.
• The rectus, in the situation where its sheath is deficient below, is separated from the peritoneum only by the transversalis fascia, in contrast to the upper layers, where part of the internal oblique also runs beneath the rectus.
• A direct inguinal hernia protrudes through a weakened area in the transversalis fascia near the medial inguinal fossa within an anatomic region known as the inguinal or Hesselbach's triangle, an area defined by the edge of the rectus abdominis muscle, the inguinal ligament and the inferior epigastric artery.
• It curves forward in the subperitoneal tissue, and then ascends obliquely along the medial margin of the abdominal inguinal ring; continuing its course upward, it pierces the transversalis fascia, and, passing in front of the linea semicircularis, ascends between the Rectus abdominis and the posterior lamella of its sheath.
• There is a common set of layers covering and forming all the walls : the deepest being the parietal peritoneum, the extraperitoneal fat, the transversalis fascia, the internal and external oblique and transversus abdominis aponeuroses, and a layer of fascia, which has different names according to what it covers ( e . g ., transversalis, psoas fascia ).
