The epidermis is the outermost layer of the skin, serving as a protective barrier against environmental threats. This article examines the anatomical structure of the epidermis, detailing its five distinct layers—stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum—along with key cellular components like keratinocytes and Merkel cells, as illustrated in a comprehensive diagram. By exploring the structure and physical characteristics of the epidermis, we uncover its essential role in safeguarding the body and maintaining skin integrity.
