Which term describes a pouch in the sigmoid colon?

• A. Duodenum
• B. Appendix
• C. Diverticulum
• D. Rectum

Answer: (C)

A diverticulum is a pouch-like outpouching of the wall of a hollow organ. In the colon, these pouches can form when mucosa and submucosa push through the muscular layer, creating a pocket. When such a pouch appears in the sigmoid colon, it’s called a diverticulum. The other terms refer to different structures: the duodenum is the first part of the small intestine, not a pouch in the sigmoid colon; the appendix is a narrow tube off the cecum, not a sigmoid pouch; the rectum is the final section of the large intestine, not a pouch.
