Which one is correct hormone with its source cells

Options

A. `alpha`-glucagon, `beta`-insulin, `delta`-somatoslatin
B. `alpha`-insulin, `beta`-glucagon, `delta`-somatostatin
C. `delta`-insulin, `alpha`-somatostain, `beta`-glucagon
D. `alpha`-somatostatin, `beta`-insulin, `delta`-glucagon.

Answer

To determine the correct hormone with its source cells, we need to identify the hormones produced by the pancreas and their respective source cells. Here’s a step-by-step breakdown:

### Step 1: Identify the Source Cells in the Pancreas
The pancreas has both endocrine and exocrine functions. The endocrine part consists of the islets of Langerhans, which contain different types of cells:
- Alpha cells
- Beta cells
- Delta cells

### Step 2: Identify the Hormones Secreted by Each Type of Cell
- **Alpha Cells**: These cells secrete **glucagon**. Glucagon is known as a hyperglycemic hormone because it increases blood glucose levels.
- **Beta Cells**: These cells secrete **insulin**. Insulin is a hypoglycemic hormone as it decreases blood glucose levels.
- **Delta Cells**: These cells secrete **somatostatin**, which plays a role in growth regulation and inhibits the secretion of other hormones.

### Step 3: Match Hormones with Their Source Cells
Now, we can summarize the hormones with their source cells:
- **Alpha Cells** → **Glucagon**
- **Beta Cells** → **Insulin**
- **Delta Cells** → **Somatostatin**

### Conclusion
Based on the information provided, the correct hormone with its source cells is:
- **Alpha cells secrete glucagon** (this is the correct pairing).

### Final Answer
The correct answer is: **Alpha cells → Glucagon**.
