stratum corneumThe stratum corneum is sometimes described as a brick wall. The corneocytes that make up the cell envelope are layers, like bricks, mortared together by lipids, that create the outer water barrier.

What are the five layers of epidermis?

The epidermis of thick skin has five layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The stratum basale is a single layer of cells primarily made of basal cells. A basal cell is a cuboidal-shaped stem cell that is a precursor of the keratinocytes of the epidermis.
