Here's why:
* Cells are categorized by their function, not location. While cheek cells are found in the lining of the mouth, they are a type of epithelial cell.
* Epithelial cells are diverse. There are different types of epithelial cells, each with a specific function. Cheek cells are squamous epithelial cells, meaning they are flat and thin.
So, while you can't call a cheek cell by a unique scientific name, you can refer to it as a squamous epithelial cell or simply an epithelial cell.
