Study Notes
Gastric Cell Types
- Mucous Cells secrete mucus and are located in the cardia and antrum of the stomach.
- Parietal Cells are responsible for gastric acid secretion and can be found in the fundus and body of the stomach.
- Chief Cells are located in the fundus and body of the stomach and secrete pepsinogen and lipase.
- Endocrine Cells (G Cells) are located in the antrum and secrete gastrin.
Gastric Cell Types and Locations
- Mucous cells are found in the cardia and antrum of the stomach, and their primary function is mucus secretion.
- Parietal cells are located in the fundus and body of the stomach, responsible for gastric acid secretion
- Chief cells reside in the fundus and body, their primary function is secretion of pepsinogen and lipase.
- Endocrine cells (G Cells) found in the antrum, secrete Gastrin.
