Options

A. Nervous tissue
B. Skin epidermis
C. Tendon
D. Smooth muscles.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which type of tissue lacks the ability to regenerate after injury. We need to analyze the options provided.

2. **Analyzing the Options**:
- **Option 1: Nervous Tissue**: Nervous tissue is primarily composed of neurons, which do not have the ability to regenerate after injury. This is because nerve cells lack the necessary cellular machinery for cell division.
- **Option 2: Skin Epidermis**: The skin epidermis has a high regenerative capacity. It can heal and regenerate after injury.
- **Option 3: Tendon**: Tendons are fibrous connective tissues that connect muscles to bones. They also have some regenerative ability, although it may be slower compared to other tissues.
- **Option 4: Smooth Muscles**: Smooth muscles have a significant capacity for regeneration. They can repair themselves after injury.

3. **Conclusion**: Based on the analysis, the only tissue that does not regenerate after injury is **nervous tissue**. Therefore, the correct answer is **Option 1: Nervous Tissue**.
