Surface layers of mouth and skin are made up of

Options

A. epithelial tissue
B. muscular tissue
C. stratified epithelial tissue
D. ciliated tissue

Answer

To answer the question "Surface layers of mouth and skin are made up of," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Question**: The question asks about the type of tissue that forms the surface layers of the mouth and skin.

2. **Review the Options**: The options provided are:
- Epithelial tissues
- Muscular tissues
- Stratified epithelial tissues
- Ciliated tissues

3. **Analyze Each Option**:
- **Muscular Tissues**: These tissues are primarily responsible for movement and are found in muscles. They do not form the surface layers of the mouth or skin. Therefore, this option is incorrect.
- **Ciliated Tissues**: These are specialized epithelial tissues found in areas such as the respiratory tract and oviduct. They are not present in the mouth or skin. Thus, this option is also incorrect.
- **Epithelial Tissues**: While epithelial tissues are present in the mouth and skin, this term is too broad and does not specify the type of epithelial tissue.
- **Stratified Epithelial Tissues**: This type of epithelial tissue consists of multiple layers of cells and is specifically found in areas subject to abrasion, such as the skin and the lining of the mouth.

4. **Conclusion**: The correct answer is **Stratified Epithelial Tissues**, as they specifically make up the surface layers of both the mouth and skin.

### Final Answer:
The surface layers of the mouth and skin are made up of **Stratified Epithelial Tissues**.
