Stratum lucidum
Stratum Lucidum
Stratum lucidum (pronunciation: /ˈstreɪtəm ˈluːsɪdəm/) is a thin, clear layer of dead skin cells in the epidermis called keratinocytes, which is visible only in areas of thick skin, such as the palms and soles.
Etymology
The term "stratum lucidum" is derived from Latin, where "stratum" means "layer" and "lucidum" means "clear" or "bright". This refers to the translucent appearance of this layer under a microscope.
Function
The stratum lucidum functions as a barrier to protect the underlying layers of the skin from environmental damage. It also helps to keep the skin hydrated by preventing water loss.
