Anatomical terminology |
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. Its quality and quantity is varies considerably. [1] It occupies the extraperitoneal space.[ citation needed]
Anteriorly, it forms the thin and fibrous [1] preperitoneal fascia [2] that is interposed between the transversalis fascia, and the parietal peritoneum. [1] [3] The preperitoneal fascia contains a variable amount of fat, loose connective tissue, and membranous tissue. [3] It is provided with its own blood supply. [2] The membranous component lies just deep to the transversalis fascia [3] and has been constured as a second layer of the transversalis fascia by some authors. [3] [4]
Posteriorly, it forms the thick and fatty pararenal fascia that surrounds the kidneys. [1]
