Which of the following hormones secreted by pancreas?

Options

A. Insulin and glucagon
B. Epinephrin and nor-epinephrin
C. Thyroxin and melanin
D. Prolactin and oxytocin

Answer

To determine which hormones are secreted by the pancreas, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Gland in Question**: The question asks about hormones secreted by the pancreas.

2. **Understand the Structure of the Pancreas**: The pancreas is a mixed gland that has both endocrine and exocrine functions. The endocrine part consists of clusters of cells known as the Islets of Langerhans.

3. **Know the Types of Cells in the Islets of Langerhans**:
- **Alpha Cells**: These cells secrete glucagon.
- **Beta Cells**: These cells secrete insulin.
- **Delta Cells**: These cells secrete somatostatin.

4. **List the Hormones Secreted by the Pancreas**: Based on the information about the Islets of Langerhans, the hormones secreted by the pancreas include:
- Insulin (from Beta Cells)
- Glucagon (from Alpha Cells)
- Somatostatin (from Delta Cells)

5. **Evaluate the Options Given**:
- **Option 1**: Insulin and Glucagon (Correct)
- **Option 2**: Apinephrine and Norepinephrine (Incorrect, these are secreted by the adrenal medulla)
- **Option 3**: Thyroxine and Melanin (Incorrect, thyroxine is secreted by the thyroid gland)
- **Option 4**: Prolactin and Oxytocin (Incorrect, these are secreted by the pituitary gland)

6. **Conclusion**: The correct answer is that the hormones secreted by the pancreas are **Insulin and Glucagon**.
