<prompt> Maximum postprandial motility is seen inAscending colonTransverse colonDescending colonSigmoid colon  <response>: Nonpropagating colonic motor activity increased in all colonic segments immediately after eating the meal p less than 0.05. The increase in motility was significantly greater in the descending colon than in the transverse and sigmoid colon p less than 0.05. In one-half of the subjects propagating contractions occurred postprandially. The movement of the intraluminal tracer occurred during both types of motility.
