How many Islets of Langerhans are present in normal human pancreas?

Options

A. 1 to 2 million
B. 2 to 3 million
C. 3 to 4 million
D. 4 to 5 million

Answer

To answer the question about the number of Islets of Langerhans present in a normal human pancreas, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Islets of Langerhans**:
- The Islets of Langerhans are clusters of endocrine cells found in the pancreas. They play a crucial role in regulating blood sugar levels by producing hormones.

2. **Identifying Cell Types**:
- The Islets consist of four distinct types of cells. Among these, three types are responsible for producing important hormones such as insulin and glucagon.

3. **Estimating the Number of Islets**:
- Research indicates that the total number of Islets of Langerhans in a normal human pancreas is estimated to be around 1 million.

4. **Providing the Range**:
- The estimate can vary, and it is commonly stated that the number of Islets can range from 1 to 2 million.

5. **Conclusion**:
- Therefore, the answer to the question is that there are approximately 1 to 2 million Islets of Langerhans present in a normal human pancreas.

### Final Answer:
The normal human pancreas contains approximately 1 to 2 million Islets of Langerhans.
