Definition[Bearbeiten]
Haustren or in Latin Haustra coli' refers to protrusions of the colon wall that give the colon a segmented appearance.
Anatomy[Bearbeiten]
The haustra are caused by the fact that the taenia running along the colon are slightly shorter than the rest of the intestinal wall. The intestinal wall is thus "gathered", so to speak. Between the hausren, the intestinal wall forms crescent-shaped folds at right angles to the direction in which it runs, which protrude into the intestinal lumen. The latter are known as plicae semilunares due to their shape. Haustren are not found on the rectum.
Physiology[Bearbeiten]
The haustra are not static structures, but dynamic. Their contraction leads to slow peristaltic segmental movements.
