Here's why:

* Squamous cells are flattened and thin cells.

* Their nucleus is often pushed to the side of the cell, giving the cell a flattened, disc-like appearance.

This is because the cytoplasm of squamous cells is stretched thin to accommodate their primary function, which is to form a protective barrier. The nucleus is displaced to make room for the cytoplasm and its cellular components.

Examples:

* Skin cells: The squamous cells of the epidermis have nuclei pushed to the side of the cell.

* Endothelial cells: These cells line blood vessels and have flattened nuclei.

While the nucleus might appear centrally located in some squamous cells, it's generally eccentric, meaning it's located off-center.
