Another peculiar feature of the large intestineis the so-called appendices epiploicae, which, however, are of littlephysiological importance. In the rectum the longitudinal muscle fibres are reduced totwo bundles, one anterior, the other posterior. They do not giverise to any formation of ridges and sacculi. In the rectal ampullathe mucous coat alone exhibits longitudinal folds, which are.
