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.
