Which layer of the skin is a clear transparent layer under the stratum corneum?

The clear, transparent layer under the stratum corneum is known as the stratum lucidum. This layer is primarily found in areas of thick skin, such as the palms of the hands and the soles of the feet. The stratum lucidum consists of a few rows of flattened, dead keratinocytes that provide an additional barrier and contribute to the overall toughness of the skin.

The presence of this layer is particularly important in protecting underlying structures from friction and shear forces, which are common in areas that experience high levels of wear and tear. The stratum corneum, comprising the outermost layer, functions as the primary barrier against environmental hazards, while the stratum lucidum adds further protection by helping reduce skin damage in high-friction areas.

In contrast, the other layers mentioned do not have the same transparent quality and serve different roles in skin health and function. The stratum granulosum is involved in the process of keratinization and begins to show characteristics of dying cells, while the stratum spinosum provides strength and flexibility through its polyhedral cells. The stratum basale serves as the base layer of actively dividing cells, contributing to the regeneration of the skin. Each layer plays a unique role, but the
