intermediate gastric gland
Quick Summary
The intermediate gastric glands, also known as true gastric glands, are located in the central part of the stomach lining. These glands are crucial for digestion, producing the majority of the stomach's digestive substances.1
These glands are composed of three main cell types:
* Zymogenic (chief) cells: Located at the base, they produce enzymes like pepsin, which digests proteins, and rennin, which curdles milk.1
* Parietal (oxyntic) cells: These cells secrete hydrochloric acid, essential for activating other digestive enzymes. They also produce intrinsic factor, vital for vitamin B12 absorption.12
* Mucous neck cells: These cells secrete mucus, which protects the stomach lining from self-digestion by diluting acids and enzymes.1
The secretion of gastric juices can be stimulated by the sight, smell, or thought of food, as well as by the presence of food in the stomach.1
