Quick Summary

Mucoid cells are specialized cells found within the mucous membranes of the body, particularly lining the digestive and respiratory tracts. These cells are responsible for producing mucus, a viscous fluid composed of water, cells, salts, and mucin.1

Mucus serves crucial functions:
* Lubrication: It moistens surfaces, aiding in the passage of food through the digestive system and keeping oral membranes moist.1
* Protection: Mucus traps inhaled particles like dust and bacteria in the nose, preventing them from reaching deeper tissues. In the stomach, a thick layer of mucus protects the organ's lining from its own acidic gastric juices and digestive enzymes.12

Mucoid cells are a primary cell type in the gastric glands of the stomach, especially in the cardiac and pyloric regions, and also line the necks of glands in other parts of the stomach.2
