What term describes small saccular protrusions of intestinal mucosa through the intestinal wall?

• A. Polyps
• B. Haustra
• C. Diverticula
• D. Adhesions

Answer: (C)

The correct term for small saccular protrusions of intestinal mucosa through the intestinal wall is diverticula. These structures are formed when weak points in the intestinal wall bulge out, creating pouches that can vary in size. Diverticula are most commonly associated with the colon and are often observed in conditions like diverticulosis, where the presence of these pouches can be noted without inflammation.

Understanding diverticula is crucial in radiography, especially when imaging the gastrointestinal tract, as these pouches can lead to complications such as diverticulitis, which may require different imaging techniques for proper diagnosis. Other terms, such as polyps, refer to growths within the intestinal lumen, haustra are the sacculations that give the colon its segmented appearance, and adhesions refer to bands of fibrous tissue that can form between organs after surgery or injury; none accurately describe the saccular protrusions characterized by diverticula.
