Haustra

From Wikipedia, the free encyclopedia

Haustra
Arteries of cecum and vermiform process.
Latin haustra coli
Dorlands/Elsevier h_03/12408675

The haustra of the colon are the small pouches caused by "sacculation", which give the colon its segmented appearance. The taenia coli runs the length of the large intestine. Because the taenia coli is shorter than the intestine, the colon become sacculated between the taenia, forming the haustra.

Haustral contractions are slow segmenting movements that occur every 30 minutes. Haustrum distends with filling, then muscle is stimulated to contract pushing contents to the next haustrum.
