Secretion of gastric juice is controlled by

Options

A. Gastrin
B. Enterogasterone
C. Secretin
D. Hepatocrinin

Answer

**Step-by-Step Solution:**

1. **Understanding Gastric Juice Secretion**: The secretion of gastric juice in the stomach is a crucial process for digestion. It involves various hormones and cells that regulate the production of gastric juice.

2. **Identifying the Key Hormone**: The primary hormone responsible for stimulating the secretion of gastric juice is gastrin. Gastrin is secreted by the G cells located in the gastric mucosa of the stomach.

3. **Role of Gastrin**: Once gastrin is released into the bloodstream, it acts on the parietal cells in the gastric glands to promote the secretion of gastric juice, which contains hydrochloric acid and digestive enzymes.

4. **Evaluating Other Options**:
- **Anterogastrone**: This hormone is secreted in the duodenum and inhibits gastric juice secretion, making it incorrect as a controller of gastric juice secretion.
- **Other Hormones**: The other options mentioned (such as hepatocrinone) do not play a direct role in the regulation of gastric juice secretion. They may have other functions, such as stimulating bile formation or regulating other digestive processes.

5. **Conclusion**: Based on the information, the secretion of gastric juice is primarily controlled by gastrin, making it the correct answer.

**Final Answer**: The secretion of gastric juice is controlled by gastrin.
