What is the name of the layer of the epidermis that consists of clear cells through which light can pass?

The layer of the epidermis that consists of clear cells through which light can pass is known as the Stratum Lucidum. This specific layer is located between the Stratum Granulosum and the Stratum Corneum and is typically found in areas of thick skin, such as the palms of the hands and the soles of the feet. The cells in the Stratum Lucidum are flattened and densely packed with a protein called eleidin, which contributes to the transparent quality of this layer. This characteristic allows light to penetrate through, giving it its name "lucidum," which means "clear" or "light."

The Stratum Lucidum plays a protective role, providing an additional layer of thickness and toughness in regions that experience a lot of friction and mechanical stress. Understanding the structure and function of this layer is essential for recognizing how skin protects underlying tissues and responds to environmental factors.
