Mucous Membrane: An Epithelium with Mucus-secreting cells, such as Goblet Cells. It forms the lining of many body cavities, such as the Digestive Tract, the Respiratory Tract, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose Connective Tissue, and an outer layer (muscularis mucosae) of Smooth Muscle Cells that separates the mucosa from submucosa.2
