becomes wavy and are called

Options

A. syncytial
B. acellular
C. tessellated
D. polygonal

Answer

To answer the question about the cells of the endothelium and mesothelium becoming wavy, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Epithelium**:
- The endothelium is the layer of cells lining blood vessels, lymph vessels, and the heart.
- The mesothelium is the epithelium lining the body's soft organs (viscera).

2. **Identify the Condition of the Cells**:
- The question asks about the condition when these cells become wavy.

3. **Explore the Options Provided**:
- **Syncytium**: This refers to a multi-nucleated condition, not relevant here.
- **Acellular**: This means there are no cells, also not applicable.
- **Tessellated**: This term describes a pattern resembling tiles, which fits the description of wavy cells in epithelium.
- **Polygonal**: This refers to the shape of cells and is not relevant to the wavy condition.

4. **Conclusion**:
- The correct term for the wavy appearance of the endothelium and mesothelium is **tessellated epithelium**.

### Final Answer:
The cells of endothelium and mesothelium become wavy and are called **tessellated epithelium**.
