Adjacent epithelial cells are joined together by

Options

A. Desmosomes
B. Oxysomes
C. Desmonemes
D. Plasmodesmata

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about how adjacent epithelial cells are joined together. This requires knowledge of cellular structures that facilitate cell adhesion.

2. **Identifying the Options**: The options provided are:
- A) Desmosomes
- B) Oxyzomes
- C) Desmonemes
- D) Plasmodesmata

3. **Analyzing the Options**:
- **Desmosomes**: These are specialized structures that connect adjacent epithelial cells, providing mechanical stability and strength by resisting shear forces.
- **Oxyzomes**: This term is not commonly used in biological contexts related to cell adhesion.
- **Desmonemes**: Similar to desmosomes but not a standard term used in cell biology.
- **Plasmodesmata**: These are channels between plant cells, not applicable to epithelial cells.

4. **Correct Answer Identification**: Based on the analysis, the correct answer is **A) Desmosomes**. They are crucial for maintaining the integrity of epithelial tissues by linking cells together.

5. **Additional Information**: Desmosomes are also referred to as macula adherens and are found in both simple and stratified squamous epithelium. They have a wide intercellular space and are also present in muscle tissue, where they help bind muscle cells together.

**Final Answer**: Adjacent epithelial cells are joined together by **Desmosomes**.
