Adrenal cortex produces

Options

A. Adrenaline
B. Epinephrine
C. Aldosterone
D. Calcitonin.

Answer

**Step-by-Step Solution:**

1. **Identify the Source of Hormones**: The adrenal gland consists of two main parts: the adrenal cortex and the adrenal medulla. Each part produces different hormones.

2. **Understand the Function of the Adrenal Cortex**: The adrenal cortex is responsible for producing several types of hormones, including corticosteroids. One of the main types of corticosteroids produced is mineralocorticoids.

3. **Identify Specific Hormones**: Among the hormones produced by the adrenal cortex, aldosterone is a key mineralocorticoid. It plays a crucial role in regulating electrolyte balance, particularly sodium and potassium levels in the body.

4. **Differentiate Between Hormones**:
- **Adrenaline (or Epinephrine)**: This hormone is produced by the adrenal medulla and is known as the "emergency hormone" because it is released during stress.
- **Aldosterone**: This is produced by the adrenal cortex and helps maintain sodium levels and blood pressure.
- **Calcitonin**: This hormone is produced by the C-cells of the thyroid gland and is involved in calcium homeostasis.

5. **Conclusion**: Based on the information, the correct answer to the question "Adrenal cortex produces" is **aldosterone**.

**Final Answer**: Aldosterone
