Inner Surface of the Anterior Abdominal Wall

Inner Surface of the Anterior Abdominal Wall Supravesical fossa Is a depression on the anterior abdominal wall between the median and medial umbilical folds of the peritoneum. Medial inguinal fossa Is a depression on the anterior abdominal wall between the medial and lateral umbilical folds of the peritoneum. It lies lateral to the supravesical fossa. Is the fossa where most direct inguinal hernias occur. Lateral inguinal fossa Is a depression on the anterior abdominal wall, lateral to the lateral umbilical fold of the peritoneum. Umbilical folds or ligaments Median umbilical ligament or fold Is a fibrous cord, the remnant of the obliterated urachus , which forms a median umbilical fold of peritoneum. Lies between the transversalis fascia and the peritoneum and extends from the apex of the bladder to the umbilicus. Medial umbilical ligament or fold Is a fibrous cord, the remnant of the obliterated umbilical artery , which forms a medial umbilical fold and extends from the side of the bladder to the umbilicus. Lateral umbilical fold Is a fold of peritoneum that covers inferior epigastric vessels and extends from the medial side of the deep inguinal ring to the arcuate line. Transversalis fascia Is the lining fascia of the entire abdominopelvic cavity between the parietal peritoneum and the inner surface of the abdominal muscles. Continues with the diaphragmatic, psoas, iliac, pelvic, and quadratus lumborum fasciae. Forms the deep inguinal ring and gives rise to the femoral sheath and the internal spermatic fascia. Is directly in contact with the rectus abdominis below the arcuate line. ◄.....Go back to the Gross Anatomy homepage
