stratum lucidum
a layer of the epidermis found only in the thick skin of the fingers, palms, and soles
Stratum lucidum is a thin, clear layer of flattened, dead cells found in the epidermis of the skin. It is present only in the thick skin of certain areas of the body such as the palms of the hands and the soles of the feet. The cells in the stratum lucidum are densely packed with a protein called keratin, which gives the layer its transparent appearance. This layer acts as a barrier to protect the skin from damage and infection. The stratum lucidum also helps to reduce friction between the epidermis and the underlying structures of the skin, improving the overall strength and durability of the skin. Additionally, this layer contributes to the skin’s ability to retain moisture, which helps to keep the skin hydrated and healthy.
