Non-cellular layer that connects epithelium to connective tissue is

Options

A. Dermis
B. Epidermis
C. Basement membrane
D. None of the above.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for a non-cellular layer that connects epithelium to connective tissue. This indicates we are looking for a structure that serves as a bridge between these two types of tissues.

2. **Identifying the Options**: The options provided are:
- Dermis
- Epidermis
- Basement membrane
- None of the above

3. **Analyzing Each Option**:
- **Dermis**: This is a layer of skin that lies beneath the epidermis and contains connective tissue. It does not serve as a direct connection between epithelium and connective tissue.
- **Epidermis**: This is the outer layer of skin, primarily made up of epithelial cells. It does not connect to connective tissue directly; rather, it is the outermost layer.
- **Basement Membrane**: This is a thin, non-cellular layer that separates epithelial tissue from the underlying connective tissue. It is composed of proteins and serves as a foundation for the epithelium.
- **None of the Above**: This option is incorrect as we have identified a suitable answer.

4. **Conclusion**: After analyzing the options, the correct answer is the **basement membrane**, as it is the non-cellular layer that connects epithelium to connective tissue.

**Final Answer**: Basement membrane
