Mineralocorticoids are produced by

Options

A. Zona fascicufata
B. Zona glomerulosa
C. Zona reticularis
D. Both (1) & (3)

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the source of mineralocorticoids, which are hormones produced in the adrenal glands.

2. **Identifying the Layers of the Adrenal Gland**: The adrenal gland consists of three main layers:
- Zona Glomerulosa (outermost layer)
- Zona Fasciculata (middle layer)
- Zona Reticularis (innermost layer)

3. **Functions of Each Layer**:
- **Zona Fasciculata**: This layer primarily produces glucocorticoids, which are involved in glucose metabolism and stress response.
- **Zona Reticularis**: This layer produces androgens, which are male sex hormones.
- **Zona Glomerulosa**: This outermost layer is responsible for producing mineralocorticoids.

4. **Identifying Mineralocorticoids**: The primary mineralocorticoid produced by the zona glomerulosa is aldosterone. Aldosterone plays a crucial role in regulating electrolyte and water balance in the body.

5. **Conclusion**: Based on the information gathered, mineralocorticoids are produced by the zona glomerulosa of the adrenal gland.

6. **Final Answer**: The correct answer is **Zona Glomerulosa**.
