Diverticula 

Diverticulum (singular) is an outpouching of the wall of the to form a sac. Diverticula (plural) may occur at any level from esophagus to colon. True diverticulum includes all three layers of the wall; mucosa, muscularis & outer serosa. False diverticula are missing muscularis & therefore very thin walled. Colonic diverticula are typically false.

True diverticula
* contains all layers of the wall of the parent organ (typically mucosa, muscular layer and serosa)
* uncommon
* e.g. Meckel diverticulum, rectal diverticulum
False diverticula
* does not contain all layers (typically mucosa pushed though defect in muscular layer)
* the vast majority of all diverticula
* e.g. colonic diverticulum
Additionally diverticula may be subdivided according to mechanism of formation into:
Pulsion diverticula
* due to increased luminal pressure
* common
* e.g. Zenker diverticulum, colonic diverticulum
Traction diverticula
* due to pulling of the wall of the viscus
* uncommon
* e.g. tracheal diverticulum
