Presence of extracellular basement mem brane is the peculiarity of

Options

A. epithelial tissue
B. connectivel tissue
C. Nervous tissue
D. muscular tissue

Answer

To answer the question regarding the presence of an extracellular basement membrane, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Tissues**:
- A tissue is defined as a group of cells that share a common origin and function. There are various types of tissues in the animal body, including epithelial, connective, nervous, and muscular tissues.

2. **Identifying the Basement Membrane**:
- The extracellular basement membrane is a thin, non-cellular layer that supports epithelial tissues. It is crucial to understand that this membrane is not present in all types of tissues.

3. **Characteristics of Epithelial Tissue**:
- Epithelial tissues consist of one or more layers of cells that cover the internal and external surfaces of the body. They can be involved in protection, secretion, and absorption.

4. **Role of the Basement Membrane**:
- The basement membrane provides elastic support to epithelial tissues and facilitates selective chemical exchange between the epithelial cells and surrounding blood vessels.

5. **Comparison with Other Tissues**:
- Connective tissues (like bone and cartilage), nervous tissues (like neurons), and muscular tissues (like smooth and cardiac muscle) do not possess a basement membrane. This distinguishes epithelial tissue from these other types.

6. **Conclusion**:
- Based on the above points, we can conclude that the presence of an extracellular basement membrane is a peculiarity of **epithelial tissue**.

### Final Answer:
The presence of extracellular basement membrane is the peculiarity of **A) epithelial tissue**.
