Mucoid cells, also known as mucous cells, are the primary cells responsible for releasing mucus in the stomach.
Mucus is crucial for protecting the stomach lining from the harsh acidic environment required for digestion. These cells are predominantly found in the gastric glands located in the cardiac and pyloric regions of the stomach.
Here's a more detailed breakdown:
-
Mucoid Cells: These specialized epithelial cells are designed to secrete a thick, viscous mucus.
-
Location: They are concentrated within the gastric glands, specifically in the cardiac and pyloric areas of the stomach.
-
Function: The secreted mucus forms a protective layer that:
- Acts as a physical barrier against the corrosive effects of gastric acid (hydrochloric acid).
- Prevents the enzyme pepsin from digesting the stomach lining itself.
- Neutralizes small amounts of acid directly at the epithelial surface
In summary, mucoid cells are the key players in producing and releasing the protective mucus that shields the stomach from self-digestion and acid damage.
