What is the function of foveolar cells?

Foveolar cells, which secrete mucin, line the surface of the stomach and the gastric. These are tall and columnar cells that contain clear mucin-containing granules.

What is fundic type mucosa?

The fundic (fundus-corpus) mucosa is built of parietal cells/chief cells while the mucosa of the antrum is built of mucin-producing cells and specialized endocrine cells. The mucosa of the incisura angularis is comprised of an admixture of corpus and antral mucosa [2], hence intermediate mucosa.

What are foveolar cells of stomach?

The surface mucus cells (foveolar cells) are mucus-producing cells that primarily line the gastric mucosa. The secreted mucus acts as a barrier to the corrosive nature of the gastric acid. The rest of the specialized cells are found deep within the gastric glands (i.e., gastric pits).

What does mucosa mean in medical terms?

(myoo-KOH-suh) 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). Also called mucous membrane.

What does mucosa look like?

A mucous membrane or mucosa is a membrane that lines various cavities in the body and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue….

Is foveolar hyperplasia serious?

A study from the 1980s suggested that hyperplastic polyps and foveolar hyperplasia in patients with atrophic corpus gastritis indicate an increased risk of gastric cancer. Large hyperplastic polyps may harbour carcinoma.

What causes foveolar hyperplasia?

Searching for “polypoid foveolar hyperplasia” indicates that this could be caused by something called h.pylori infection as well as auto-immune gastritis.

What are the subdivisions of mucosa?

The mucosa has subdivisions called surface epithelium, lamina propria, and muscular layer. Its major functions include secretion of enzymes, mucus, and hormones, absorption of digested foodstuffs, and protection against bacterial invasion.

Is intestinal metaplasia of the stomach reversible?

In brief: Yes. Metaplasia is a reversible change in cell types. However, for the change to reverse, the insult, stimulus, factor causing the change has to be removed. Metaplasia is a reversible change in cell types.

What is the plural of mucosa?

The plural form of mucous membrane is mucous membranes.
