Lucidum
Lucidum
The stratum lucidum, which is present in the thick skin of the palms and soles, is absent in thin skin
The stratum lucidum is absent from most epidermis, except for in areas with thick skin, such as the palms of the hands and soles of the feet. The stratum lucidum is a clear layer of dead skin cells found between the stratum granulosum and stratum corneum.
In thin skin, the epidermis lacks a stratum lucidum layer found in thick skin. Additionally, thin skin has fewer layers of the stratum corneum, which is the outermost layer of the epidermis. Overall, thin skin is more flexible and sensitive compared to thick skin.
Lucidum
Yes, the stratum corneum is notable for its keratin content.
The stratum corneum is the outermost layer of the skin. It is not the foundational layer of the skin.
The Stratum Lucidum
The stratum corneum is a part of the layer of skin called the epidermis.
Stratum lucidum (in thick skin) is a well defined epidermal layer found under the corneum region of the skin of the palms and soles. Main function of this stratum is to help the skin handle friction and also waterproof it. It is a thin transitional layer of epidermis found between the 'horny' and 'granular' layers.
Skin cells start in the stratum spinosum and move up the stratum granulosum, then to the stratum licidum, and stratum corneum. This is the epidermis inside out layers and growth process.
The stratum basale is found in the skin. It is one of the layers of the epidermis.
