The transversalis fascia (or transverse fascia) is the fascial lining of the anterolateral abdominal wall [1] [2] situated between the inner surface of the transverse abdominal muscle, and the preperitoneal fascia. [3] [2] It is directly continuous with the iliac fascia, [2] the internal spermatic fascia, [citation needed] and pelvic fascia. [2]
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...
The fibrous tissue of the linea alba, which separates the right and the left abdominal muscles, serves as a guide for where to cut. After opening the fascia, the abdominal cavity, or peritoneum, is entered. The surgeon then looks for evidence of injury, infection, or disease.
The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a complex, [1]: 1137 multilayer arrangement of fascial and aponeurotic layers forming a separation between the paraspinal muscles on one side, and the muscles of the posterior abdominal wall (quadratus lumborum, and psoas major [1]: 1137 ) on the other.
Extraperitoneal fascia (also: endoabdominal fascia or subperitoneal fascia) is a fascial plane – consisting mostly of loose areolar connective tissue – situated between the fascial linings of the walls of the abdominal and pelvic cavities (transversalis fascia, anterior layer of thoracolumbar fascia, iliac fascia, and psoas fascia) externally, and the parietal peritoneum internally.
Without a stable spine, one aided by proper contraction of the TVA, the nervous system fails to recruit the muscles in the extremities efficiently, and functional movements cannot be properly performed. [2] The transverse abdominal and the segmental stabilizers (e.g. the multifidi) of the spine have evolved to work in tandem.
The end of the epididymis is connected to the vas deferens. The vas deferens ends with an opening into the ejaculatory duct at a point where the duct of the seminal vesicle also joins the ejaculatory duct. [1] The vas deferens is a partially coiled tube which exits the abdominal cavity through the inguinal canal.
The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body cavity enclosed by the abdominal muscles, at the front and to the sides, and by part of the vertebral column at the back. Lower ribs can also enclose ventral and lateral walls. The abdominal ...
