This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: G.I.T, Subject name: Physiology
Maximum postprandial motility is seen in 
Select and explain. 
A. Ascending colon, B. Transverse colon, C. Descending colon, D. Sigmoid colon
C: Descending colon
Answer: C: Descending colon 
Explanation: 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.
