The inner part of the stomach wall is the gastric mucosa a mucous membrane that forms the lining of the stomach. the membrane consists of an outer layer of columnar epithelium, a lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.
The appendix has a mucosa resembling the colon but is heavily infiltrated with lymphocytes. Transition between the different types of epithelium occurs at the junction between the oesophagus and stomach; between the stomach and duodenum, between the ileum and caecum, and at the pectinate line of the anus.

The gastric glands open into gastric pits in the mucosa. The gastric mucosa is covered in surface mucous cells that produce the mucus necessary to protect the stomach's epithelial lining from gastric acid secreted by parietal cells in the glands, and from pepsin, a secreted digestive enzyme. Surface mucous cells follow the indentations and ...
The mucosa is the innermost layer of the gastrointestinal tract. The mucosa surrounds the lumen, or open space within the tube. This layer comes in direct contact with digested food . The mucosa is made up of: Epithelium – innermost layer. Responsible for most digestive, absorptive and secretory processes.
The gastric folds consist of two layers: Mucosal layer – This layer releases stomach acid. It is the innermost layer of the stomach. [5] It is affected by the hormone histamine, which signals it to release hydrochloric acid (HCl). Sub-mucosal layer – This layer consists of different vessels and nerves, ganglion neurons, and adipose tissue ...
For instance, mucosa in the stomach protects it from stomach acid, [2]: 384, 797 and mucosa lining the bladder protects the underlying tissue from urine. [8] In the uterus, the mucous membrane is called the endometrium, and it swells each month and is then eliminated during menstruation. [2]: 1019
Foveolar cells or surface mucous cells are mucus-producing cells which cover the inside of the stomach, protecting it from the corrosive nature of gastric acid. [1] [a] These cells line the gastric mucosa and the gastric pits. Mucous neck cells are found in the necks of the gastric glands.
