Document Summary

Continuous, but subdivided for descriptive purposes into anterior, right and left lateral walls, and posterior wall. Wall consists of skin, subcutaneous tissue, muscles and their aponeuroses, deep fascia, extraperitoneal fat, and parietal peritoneum skin attaches loosely to subcutaneous tissue except at the umbilicus where it adheres firmly. Investing fascial covers the external aspect of the 3 muscle layers of the anterolateral abdominal wall and their aponeuroses. Endo-abdominal fascia is the membranous sheet of varying thickness that lines the internal aspect of the abdominal wall. Although continuous, different parts of this fascia can be named according to the muscle or aponeurosis it is lining - e,g, portion lining the deep surface of the transverses abdomens muscle or aponeurosis is transversalis fascia. Parietal peritoneum lines the abdominal cavity and is located internal to the transversalis fascia - it is separated from the transversalis fascia by a variable amount of extra-peritoneal fat. All muscles end anteriorly in a strong sheet-like aponeurosis.
