Definition of epidermis

The word "epidermis" comes from the Greek word "ἐπι" (epi), which means "upon" or "upon", and the Greek word "δερμας" (derma), which means "skin". Together, these words form the Greek word "ἐπιδερμας" (epidermis), which means "skin that is upon". In modern English, the word "epidermis" is used to describe the outermost layer of the skin, which is primarily composed of non-living cells. This layer is responsible for protecting the underlying layers of the skin from external injury and environmental factors, such as bacteria, viruses, and UV radiation. In biology and medical science, the term "epidermis" is used to describe the outermost layer of the skin, which is primarily composed of non-living cells. This usage is common in many different contexts, from dermatology and skin health to biochemistry and cell biology, where it is used to describe the outermost layer of the skin, which is primarily composed of non-living cells, and which plays a critical role in protecting the underlying layers of the skin from external injury and environmental factors. In computing and information technology, the term "epidermis" is sometimes used to describe a layer or interface that is designed to protect or shield a system or application from external injury or environmental factors, particularly in relation to cybersecurity and network defense. This usage is less common than the more traditional usage, but it is still used in some contexts, particularly in relation to cybersecurity and network defense, where it is used to describe a layer or interface that is designed to protect or shield a system or application from external injury or environmental factors. In all of these contexts, the word "epidermis" is used to describe the outermost layer of the skin, which is primarily composed of non-living cells, or a layer or interface that is designed to protect or shield a system or application from external injury or environmental factors.
