What is NOT an epithelial membrane in the human body ?

Options

A. Mucous membrane
B. Serous membrane
C. Cutaneous membrane
D. Endocardium membrane

Answer

To determine which option is NOT an epithelial membrane in the human body, we can analyze each option provided:

### Step-by-Step Solution:

1. **Identify the Options**: We need to evaluate the given options, which are:
- Mucous membrane
- Serous membrane
- Cutaneous membrane
- Endocardium membrane

2. **Evaluate Mucous Membrane**:
- The mucous membrane is an epithelial membrane that lines various cavities and surfaces in the body, including the respiratory and digestive tracts.
- **Conclusion**: Mucous membrane IS an epithelial membrane.

3. **Evaluate Serous Membrane**:
- The serous membrane is another type of epithelial membrane that lines body cavities and covers organs, providing a smooth surface for movement.
- **Conclusion**: Serous membrane IS an epithelial membrane.

4. **Evaluate Cutaneous Membrane**:
- The cutaneous membrane refers to the skin, which is the largest organ of the body and serves as a protective barrier. It is composed of epithelial tissue.
- **Conclusion**: Cutaneous membrane IS an epithelial membrane.

5. **Evaluate Endocardium Membrane**:
- The endocardium is the inner lining of the heart chambers and is made up of endothelial cells, which are a type of epithelial tissue. However, it is specifically classified as a type of connective tissue lining rather than a traditional epithelial membrane.
- **Conclusion**: Endocardium membrane is NOT classified as a typical epithelial membrane.

### Final Answer:
The option that is NOT an epithelial membrane in the human body is **Endocardium membrane**.
