The inferior surface, however, has peritoneum covering it. This surface's right side is narrow and its left side is wider. It rests on the duodenojejunal flexure and on some of the jejunum's coils. The left extremity lies on the left colic flexure.

The anterior border keeps the anterior and the inferior surface apart. The transverse mesocolon's two layers separate from each other on this border. One layer goes up and over the anterior surface, while the other goes back over the inferior surface.

The inferior border keeps the inferior surface apart from the posterior. Under its right extremity the superior mesenteric vessels appear.

The superior border is sharp and thin on the left, near the tail and flat and blunt on the right. The omental tuberosity is where it ends on the right. It is close to the celiac artery, where the hepatic artery flows to the right, over the gland. The lienal artery goes left on this border.
