Pathology Ch. 17: Lower Gi Tract

Front 1

Colonic diverticular result from

Back 1

The unique structure of the muscularis propria of the colon and elevated intraluminal pressure

Front 2

Diverticula are most common in?

Back 2

the sigmoid colon

Front 3

How does the unique structure of the muscularis propria cause diverticula in the colon?

Back 3

The external longitudinal layer of muscularis propria actually forms the teniae coli instead of reinforcing the gaps created where nerves, arterial vasa recta, and their connective tissue sheath penetrate the innercircular layer of muscle

Front 4

How does increased luminal pressure cause diverticula?

Back 4

Is due to exaggerated peristaltic contractions with spasmodic sequestration of bowel segments.

Front 5

Because the wall of the diverticulum is supported only by the muscularis mucosa and a thin layer of subserosal adipose tissue, inflammation and increased pressure within an obstructed diverticulum can lead to

Back 5

Perforation

Front 6

Diverticula are most commonly found in

Back 6

around the teniae coli of the sigmoid colon

Front 7

Hypertrophy of what is common in the affected bowel of diverticuli
