Which anatomical feature corresponds to the left border of the stomach that is longer and convex?

• A. Greater curvature of the stomach
• B. Lesser curvature of the stomach
• C. Haustra
• D. Ileus

Answer: (A)

The left border of the stomach is formed by the greater curvature, which is the longer, convex margin that runs from the gastroesophageal junction to the pylorus. This outward curve makes it the prominent left-side border. The lesser curvature is the shorter, inner, concave border on the stomach’s medial side, facing the liver. Haustra are pouches of the colon, and ileus refers to a bowel obstruction condition, not a stomach border. So the feature that corresponds to the left border being longer and convex is the greater curvature.
