Mucosa: The moist, inner lining of some organs and body cavities (such as the nose, mouth, lungs, and stomach). Glands in the mucosa make mucus (a thick, slippery fluid). The muscoa consists of a surface epithelium, a lamina propria, and, in most of the length of the gastrointestinal tract (lower esophagus, stomach, small intestine, colon, and rectum), a muscularis mucosae.
