Description

This anatomical image presents a clear view of a small duodenal ulcer located on the inner lining of the duodenum. The lesion appears as a well-defined, round, pale crater surrounded by slightly inflamed mucosa. The smooth folds of the intestinal wall are visible in contrast to the disrupted area, emphasizing the localized nature of the ulcer. The open sectional perspective provides a focused and educational depiction of early-stage peptic ulcer disease in the duodenum.
