The anterior abdominal wall is at first represented by the somatopleure of the overhanging head and tail folds. The Formation of the Umbilical Cord 307 Ectopia vesicae and absence of an anterior abdominal wall (eventration) have already been discussed (1937, 1938), and here remarks will be confined to herniation which results from maldevelopment of the umbilical cord and neighbouring parietes. Understanding the Anterolateral Abdominal Wall Musculoaponeurotic wall is made up of several layers: Skin Camper fascia Scarpa fascia External oblique Internal oblique Transversusabdominis Transversalis fascia Extraperitoneal fat Parietal peritoneum Ventral body wall defects include ectopia cordis, bladder exstrophy, and the abdominal wall malformations gastroschisis and omphalocele. The kidneys are reddish-brown bean-shaped structures located retroperitoneally along the posterior abdominal wall (Fig. The five muscles in the abdominal wall are divided into two groups: (1) two vertical muscles situated near the midline of the body and (2) three flat muscles located laterally and stacked on top of each other. The etiology of ectopia cordis, gastroschisis, and bladder exstrophy is not known, but they may be linked to abnormalities in the lateral body wall folds responsible for closing the thoracic, abdominal, and pelvic portions of the ventral body wall. Embryology of the abdominal wall By the end of the fifth week of development, an embryo is a flat disk consisting of three layers: ectoderm, mesoderm, and endoderm.

Our data, therefore, show that the ventral body wall is formed by differential dorsoventral growth in the dorsal part of the body. Is an avascular fibro-tendinous raphe formed by the interlacing fibers of the aponeurosis of the three lateral muscles of anterior abdominal wall (external oblique, internal oblique and transversus abdominis). The "anatomic" or "embryologic" anal canal is only 2.0 cm long, extending from the anal verge to the dentate line, the level that corresponds to the proctodeal membrane.
