Somatostatin is secreted by :

Options

A. Islets of Langerhans
B. Brunner's glands
C. Chief cells
D. Goblet cells

Answer

**Step-by-Step Solution:**

1. **Understanding Somatostatin**: Somatostatin is a hormone that plays a crucial role in regulating the endocrine system and inhibiting the secretion of other hormones. It is often referred to as the growth hormone-inhibiting hormone.

2. **Identifying the Source of Somatostatin**: The question asks where somatostatin is secreted from. The primary source of somatostatin in the body is the Islet of Langerhans, which are clusters of cells in the pancreas.

3. **Evaluating the Options**:
- **Option 1: Islet of Langerhans**: This is the correct answer as these cells secrete somatostatin.
- **Option 2: Burner's Gland**: This option is incorrect. Burner's glands secrete alkaline fluid to protect the mucosa from stomach acid.
- **Option 3: Chief Cells**: This option is also incorrect. Chief cells are found in the stomach and secrete pepsinogen, not somatostatin.
- **Option 4: Goblet Cells**: This option is incorrect as well. Goblet cells are responsible for secreting mucus in the intestines and do not secrete somatostatin.

4. **Conclusion**: Based on the evaluation of the options, the correct answer is that somatostatin is secreted by the Islet of Langerhans.

**Final Answer**: Somatostatin is secreted by the Islet of Langerhans.
