Transit of foods and contents from the mouth to the anus has received an exact control. The peristaltic movement in the gastrointestinal tract is regulated by the close interaction of cells such as the mucous, the enteric neurons, the smooth muscles, and the interstitial cells of Cajal that compose the intestines organization. However, the function of these cells is still a lot of uncertain points. Therefore, I have elucidated the interactive mechanisms between them and their changes at the pathological condition and at the same time clarified their individual functions. Moreover, I also pursue the identification of the inhibitory neurotransmitter and the change of its role by aging.
