Editing Diverticulum (section)

==Classification==
Diverticula are described as being true or false depending upon the layers involved:

*False diverticula (also known as "pseudodiverticula") do not involve muscular layers or adventitia. False diverticula, in the gastrointestinal tract for instance, involve only the [[submucosa]] and [[mucosa]], such as [[Zenker's diverticulum]].<ref name=":0" /> False diverticula are typically synonymous with [[Pulsion diverticulum|pulsion diverticula]], which describes the mechanism of formation as increased intraluminal pressure.
*True diverticula involve all layers of the structure, including [[muscularis propria]] and [[adventitia]], such as [[Meckel's diverticulum]].<ref name=":0">{{Cite book | last1=Townsend | first1=Courtney M.
