Stratified squamous Epithelium consists of : -

Options

A. Outer most layer squamous & Inner most is cuboidal
B. Outer most layer cubummer & Inner most is squamous
C. Outer most layer columner & Inner most is cuboidal
D. Outer most layer cuboidal & Inner most is columnar

Answer

**Step-by-Step Solution:**

1. **Understanding Stratified Squamous Epithelium**: The term "stratified" indicates that this type of epithelium consists of multiple layers of cells. The word "squamous" refers to the shape of the cells in the outermost layer.

2. **Identifying the Layers**: Stratified squamous epithelium has three distinct layers:
- **Innermost Layer (Germinated Layer)**: This layer consists of cells that are either columnar or cuboidal in shape. These cells are responsible for continuous cell division (mitosis) to produce new cells.
- **Middle Layer (Intermediate Layer)**: The cells in this layer are polyhedral (many-sided) and have rounded nuclei.
- **Outermost Layer (Superficial Layer)**: The cells here are flat and have transversely elongated nuclei, which are referred to as squamous cells.

3. **Conclusion**: Based on the structure of stratified squamous epithelium, we can summarize that it consists of:
- Innermost layer: Columnar or cuboidal cells
- Middle layer: Polyhedral cells
- Outermost layer: Squamous cells

4. **Correct Answer**: Therefore, the correct option is that the stratified squamous epithelium consists of an outermost layer of squamous cells and an innermost layer of cuboidal cells.
