👉 Spolium is a medical term that refers to the outer layer of the gastrointestinal tract, specifically the lining of the mouth and esophagus. The spolium includes both the smooth muscle layers and the epithelial cells that line the walls of the gut. These layers help protect the digestive system from damage caused by acids, gases, and other substances in the digestive process. Understanding the function and structure of the spolium is crucial for maintaining healthy gastrointestinal health.
