What are diverticuli?

Diverticuli are small, bulging pouches that can form in the lining of the digestive system, particularly in the large intestine (colon). They develop when weak spots in the intestinal wall give way, leading to the formation of these protrusions. This condition is known as diverticulosis, and while many people with diverticululi may not experience any symptoms, complications can arise, such as inflammation or infection, leading to diverticulitis.

The other options represent different medical conditions that do not accurately define diverticuli. Inflamed blood vessels in the brain relate to conditions such as vasculitis or hemorrhagic stroke. Fluid-filled cavities in the spinal cord might reference conditions like cysts or syringomyelia. Growths on the small intestine could indicate tumors or polyps, which are distinct from diverticuli. Understanding the correct definition helps clarify the context of gastrointestinal health and related conditions.
