Steroid hormones have an effect

Options

A. Slow and short term
B. Fast and short term
C. Fast and long lasting
D. Slow and long lasting

Answer

### Step-by-Step Solution:

1. **Understanding Steroid Hormones**: Steroid hormones are a class of hormones that are derived from cholesterol. They include hormones produced by the adrenal cortex, such as aldosterone, cortisol, and sex hormones.

2. **Types of Steroid Hormones**: The adrenal cortex has three zones, each producing different steroid hormones:
- **Zona Glomerulosa**: Produces mineralocorticoids (e.g., aldosterone).
- **Zona Fasciculata**: Produces glucocorticoids (e.g., cortisol).
- **Zona Reticularis**: Produces androgens (sex hormones).

3. **Effects of Steroid Hormones**: Steroid hormones have various effects on the body. They can influence metabolism, immune response, and inflammation.

4. **Speed and Duration of Action**:
- Steroid hormones typically have a **slow onset of action** because they often work by altering gene expression and protein synthesis.
- However, they can also have **long-lasting effects** due to their ability to modify cellular functions over time.

5. **Clinical Use**: Steroid hormones, particularly glucocorticoids like cortisol, are used clinically for their anti-inflammatory and immunosuppressive properties. They provide quick relief from inflammation and allergies, indicating a rapid effect.

6. **Conclusion**: Given the characteristics of steroid hormones, their effects are generally **slow to initiate but long-lasting**. Therefore, the correct answer to the question is **"slow and long lasting."**

### Final Answer:
**Steroid hormones have a slow and long-lasting effect.**
