Mucosal cells

Patent Granted The gastric mucosa is the mucous membrane layer of the stomach which contains the glands and the gastric pits. In humans it is about 1 mm thick and its surface is smooth, soft, and velvety. It consists of epithelium, lamina propria, and the muscularis mucosae. In its fresh state, it is of a pinkish tinge at the pyloric end and of a red or reddish-brown color over the rest of its surface. In infancy it is of a brighter hue, the vascular redness being more marked.
