True or False? Diverticuli Classification

A False Diverticulum is one that in which 2 layers(mucosa & submucosa) penetrate a weakness in the muscular layer. So those 2 layers kind of punch through the muscle, and end up being covered only by serosa.

A True Diverticulum is one in which all 3 layers of the intestinal wall, including the muscular layers, outpouch. So one can argue that the appendix is a true diverticulum.

Note that diverticulosis, false diverticuli are involved. Also, congenitally abnormal diverticuli tend to be of the 'true' type.
