Which one of the following is incorrectly match of the source and the hormone ?

Options

A. Glucagon – Beta cells
B. Somatostatin – Delta cells
C. Corpus luteum -ovary
D. Insulin –b-cells of pancreas

Answer

To solve the question regarding the incorrect match of the source and the hormone, we can follow these steps:

### Step 1: Understand the sources of hormones
- 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, and delta cells.

### Step 2: Identify the hormones produced by each cell type
- **Alpha cells**: Produce glucagon.
- **Beta cells**: Produce insulin.
- **Delta cells**: Produce somatostatin.

### Step 3: Analyze the options provided
- The question asks which option incorrectly matches the source with the hormone.
- The first option states that glucagon is produced by beta cells.

### Step 4: Verify the correctness of the first option
- Since glucagon is actually produced by alpha cells, not beta cells, this option is incorrect.

### Step 5: Check the other options
- **Somatostatin** is produced by delta cells, which is correct.
- **Insulin** is produced by beta cells, which is also correct.
- **Relaxin** is produced by the corpus luteum in the ovary, which is correct.

### Conclusion
- The only incorrect match is the first option: glucagon from beta cells. Therefore, the answer to the question is that the incorrect match is glucagon from beta cells.
