“…The stimuli, for example, pinching or longitudinal as well as transversal stretching of the intestinal wall (4,5,7,9,13,15,17), insertion of the bolus into the intestinal lumen (4,5,8,13), distension of the intestinal wall by insertion of the balloon (5,16,21), application of NaCl-crystal on the serosal surface or electric stimulation of the intestinal wall (2,3,4,5,7,17,19) would be capable of producing the mixed responses of different origin. Bozler (7) and Borchardt (6) tried to stimulate the mucosa only, but their results do not agree with ours in that they could not observe the inhibitory effect anally, so that Bozler doubt whether the inhibition should be considered as a part of the so-called myenteric reflex effects or not.…”
