Answer 1

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.

What is keratinocytes?

• Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
• Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
• They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
• The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
• A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
• The skin's epidermis is made up of this kind of epithelium.
