"stratum lucidum" の定義と意味

What is "stratum lucidum"?

The stratum lucidum is a thin, transparent layer of skin located between the stratum granulosum and the stratum corneum. It consists of flattened, densely packed cells that lack nuclei and other cellular organelles. This layer is responsible for enhancing the durability and resilience of the skin, particularly in areas subjected to constant friction and pressure. It plays a crucial role in maintaining the integrity and barrier function of the epidermis.
