Interstitial Cells of Cajal

Interstitial cells of Cajal are specialized cells found in the gastrointestinal tract. They act as pacemakers, helping to coordinate the rhythmic contractions of the smooth muscle that moves food through the digestive system. By generating electrical signals, these cells facilitate digestive motility, ensuring that the muscles contract in a synchronized manner. Their proper functioning is crucial for effective digestion; if they are impaired, it can lead to digestive disorders. Essentially, think of them as facilitators that help the digestive system keep moving smoothly.
