They are an integral part of the enteric nervous system, which regulates the functions of the gastrointestinal system. These cells have a unique structural organization that enables their primary function: the contraction and relaxation necessary for the propulsion of gastrointestinal contents. Smooth muscle cells in the enteric system possess unique attributes that distinguish them from other smooth muscle cells in the body. One crucial function is peristalsis, where these cells contract in a coordinated manner, generating a wave of contraction and relaxation. This peristaltic movement facilitates the movement of food particles through the digestive tract, playing a vital role in the digestion and absorption processes in animals. Additionally, these cells are responsible for maintaining the tone of gastrointestinal sphincters, controlling passage and preventing one-sided movement of the contents. Enteric smooth muscle cells are also involved in local immune responses of the gastrointestinal tract. They can communicate with local immune cells and secrete cytokines or other signaling molecules in response to infectious organisms, which makes them crucial mediocellular players in gastrointestinal homeostasis and response to disease. Their interactions with other cell types, such as neurons, myofibroblasts, and interstitial cells of Cajal, further contribute to these cells' role in maintaining the physiological functions of the gastrointestinal system. Overall, enteric smooth muscle cells provide an indispensable contribution to the complex operations of the digestive tract.
