Other mucus-secreting cells are the mucous neck cells in the necks of the gastric glands. [2]: 257 Surface mucous cells have large quantities of mucin granules in their apical (top) surface and project short microvilli into the lumen of the stomach. [2]: 257 Mucins are large glycoproteins that give the mucus its gel-like properties. [3]
The mucus produced here is less acidic than that produced by the mucous neck cells. Fundic glands found in the fundus and also in the body have another two cell types–gastric chief cells and parietal cells (oxyntic cells). Foveolar cells (surface mucous cells) are mucus-producing cells which cover the inside of the stomach, protecting it from ...
Gastric juice contains hydrochloric acid, pepsinogen and mucus. Hydrochloric acid is secreted by parietal cells, pepsinogen is secreted by gastric chief cells and mucus is secreted by mucous neck cells. [3]
Several types of endocrine cells are found in the gastric glands. The pyloric glands contain gastrin -producing cells ( G cells ); this hormone stimulates acid production from the parietal cells. Enterochromaffin-like cells (ECLs), found in the oxyntic glands release histamine , which also is a powerful stimulant of the acid secretion.
Mucous cells of the stomach lining secrete mucus (pink) into the lumen. Mucus (/ ˈ m j uː k ə s /, MEW-kəs) is a slippery aqueous secretion produced by, and covering, mucous membranes. It is typically produced from cells found in mucous glands, although it may also originate from mixed glands, which contain both serous and mucous cells.
Chief cells are part of fundic gland polyps (here shown in high magnification). [11]In gastric tissue, a loss of parietal cells due to chronic inflammation has been shown to affect chief cell differentiation and can induce chief cells to transdifferentiate back into neck cells and can lead to the formation of mucus cell metaplasia known as spasmolytic polypeptide expressing metaplasia (SPEM ...
Along with tea, sipping on clear hot bone broth can also help to moisturize your mucous membranes and promote better mucus flow, says Dr. Mercola. Broths are rich with amino acids, minerals, and ...
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue .
