The hormone that stimulates the release of pancreatic juice is

Options

A. secretin
B. glucagon
C. inhibin
D. insulin

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the hormone that stimulates the release of pancreatic juice. Pancreatic juice is essential for digestion as it contains enzymes that help break down carbohydrates, proteins, and fats.

2. **Identifying the Options**: The options provided are:
- a) Secretin
- b) Glucose
- c) Inhibin
- d) Insulin

3. **Analyzing Each Option**:
- **Secretin**: This hormone is produced by the S cells in the duodenum (the first part of the small intestine) in response to acidic chyme entering from the stomach. Its primary role is to stimulate the pancreas to release bicarbonate and pancreatic enzymes, which are crucial for digestion.
- **Glucose**: This is a simple sugar and not a hormone. It is a primary energy source for the body but does not stimulate pancreatic juice release.
- **Inhibin**: This hormone is involved in the regulation of reproductive functions and does not play a role in stimulating pancreatic juice.
- **Insulin**: This hormone regulates blood sugar levels and is produced by the pancreas, but it does not stimulate the release of pancreatic juice.

4. **Conclusion**: Based on the functions of the hormones analyzed, the correct answer is **Secretin**. It is specifically known for its role in stimulating the release of pancreatic juice and bicarbonate secretion.

5. **Final Answer**: The hormone that stimulates the release of pancreatic juice is **Secretin**.
