Cheek cells are stratified.
Stratified Squamous Epithelium
Cheek cells are composed of stratified squamous epithelium. This means they consist of multiple layers of cells, with the uppermost layer being squamous (flat and scale-like). The topmost squamous layer is called the stratum corneum.
Why Stratified?
The stratified nature of cheek cells is crucial for their function. Here's why:
- Protection: The multiple layers provide a protective barrier against abrasion and mechanical stress within the oral cavity. This is necessary due to the constant exposure to food, liquids, and other substances.
- Continuous Renewal: Cells from the deeper layers constantly divide and replace the cells that are shed from the surface. This allows for continuous renewal and repair of the epithelium.
In summary, the classification of cheek cells as stratified squamous epithelium reflects their multilayered structure and protective function within the mouth.
