The omentum usually extends over a large area. Arising from the greater curvature of the stomach it crosses the transverse colon and descends in front of the abdominal viscera, occasion ally down to the symphysis. Its right upper edge faces the liver, and on its left is the spleen ; its anterior surface faces the parietal peritoneum, i.e., the abdominal wall, and its posterior surface passes over the viscera. The omental portion between the stom ach and colon is called the gastrocolic ligament, and the portion below the colon is the “apron.”
