| Question | Answer |
|---|---|
| Flattened cells that look squished or smeared onto the basement membrane | Squamous |
| Cells that are about as wide as they are tall. They may appear more spherical or trapezoidal | Cuboidal |
| Cells that are taller than they are wide | Columnar |
| Cells change shape when under tension. They appear cuboidal or bubble-shaped when relaxed but change to squamous when pulled | Transitional |
| A single row of cells in which every cell touches the basement membrane and the apical surface | Simple |
| Two or more layers of cells. Only the deepest layer touches the basement membrane and only the most superficial layer touches the apical surface | Stratified |
| All cells touch the basement membrane but not all of them reach the apical surface. The nuclei are at varying heights, making this tissue appear to have several layers when it really only has one | pseudostratified |
| Dead, keratin-filled, very flattened cells are constantly shed and replaced | Stratum corner |
| Proteins and fats are dispersed through dead cells so they look clear | Stratum lucid |
| Cells are bound together via desmosomes. When the cells shrink during some kinds of slide preparation they appear spiny. | Stratum spinous |
| Deepest, single layer of cells in contact with the basement membrane. These immature cells do not look squamous | Stratum basale |
