Figure 2 Normal small intestinal and colonic MMCs. Note how the phasic contractions of the small intestine have a shorter duration and different character from the contractions of the colon. The numbers on the left-side indicate the distance in centimeters of the small intestine (SI) from the pylorus. The letter C refers to the colon and the numbers are the distance in cm from the ileocolonic junction.
