The hormone involved in the discharge of pancreatic juice in mammal is called-

Options

A. Gastrin
B. Secretin
C. Secretin & CCK
D. Enterogastrone

Answer

To answer the question regarding the hormone involved in the discharge of pancreatic juice in mammals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Role of Hormones in Digestion**:
- Hormones play a crucial role in the digestive process by regulating various functions, including the secretion of digestive juices from the pancreas.

2. **Identifying the Relevant Hormones**:
- The two primary hormones that stimulate the pancreas to release its juices are Secretin and Cholecystokinin (CCK).

3. **Evaluating the Options**:
- **Gastrin**: This hormone primarily stimulates gastric acid secretion and does not directly stimulate pancreatic juice secretion.
- **Secretin**: This hormone is released in response to acidic chyme entering the small intestine and stimulates the pancreas to release bicarbonate and digestive enzymes.
- **Cholecystokinin (CCK)**: This hormone is released in response to fats and proteins in the small intestine and also stimulates the pancreas to secrete digestive enzymes.
- **Anterogastron**: This hormone inhibits gastric activities and is not involved in stimulating pancreatic juice secretion.

4. **Conclusion**:
- The correct answer is that the hormones involved in the discharge of pancreatic juice in mammals are **Secretin and Cholecystokinin (CCK)**.

### Final Answer:
The hormone involved in the discharge of pancreatic juice in mammals is **Secretin and Cholecystokinin (CCK)**.
