Which of the following is an avascular tissue?

Options

A. Connective
B. Epithelial
C. Muscular
D. Nervous

Answer

To determine which of the following tissues is avascular, we need to understand what avascular means and analyze each option provided.

### Step-by-Step Solution:

1. **Understand the term "avascular":**
- Avascular refers to tissues that do not have a blood supply. This means that these tissues do not contain blood vessels and rely on diffusion for nutrient and waste exchange.

2. **Analyze the options:**
- **Option 1: Connective Tissue**
- Connective tissues are generally vascular, meaning they have a blood supply. They play a role in connecting different tissues and organs in the body.

- **Option 2: Epithelial Tissue**
- Epithelial tissues are avascular. They do not have blood vessels and receive nutrients through diffusion from underlying connective tissues. Epithelial tissues form the outer lining of organs and body surfaces.

- **Option 3: Muscular Tissue**
- Muscular tissues are vascular. They require a blood supply to provide oxygen and nutrients for muscle contraction and function.

- **Option 4: Nervous Tissue**
- Nervous tissues are also vascular. They need a constant supply of oxygen and nutrients to function properly, especially since they are involved in rapid signaling and communication in the body.

3. **Conclusion:**
- Based on the analysis, the only tissue that is avascular is **Epithelial Tissue** (Option 2).

### Final Answer:
The avascular tissue among the options provided is **Epithelial Tissue**.
