What term is used to refer to several layers of cells in histology?

The term "strata" refers to multiple layers of cells in histology. In histological terms, "strata" is often used to describe layers of cells that can be observed in certain types of tissues, particularly in epithelial tissue, where cells can be organized into distinct layers. This layering is important for various functions of these tissues, such as protection and absorption.

For example, in stratified epithelial tissue, multiple layers of cells help provide a barrier that protects underlying tissues from damage or pathogens. The stratification allows for the renewal of cells, where the outermost cells can be shed and replaced by those from lower layers. Hence, the use of "strata" captures this concept of layering, which is a fundamental aspect of understanding the structure and function of various tissues in histology.
