Quizplus · Accepted Answer

The stratum basale is the deepest layer of the epidermis and is responsible for the production of new skin cells. In the nail bed and matrix, it produces the cells that form the nail plate. The stratum corneum is the outermost layer of the epidermis and forms the tough, protective barrier of the skin. The stratum lucidum is a thin, clear layer of the epidermis found only in thick skin, such as the palms and soles of the feet. The stratum spinosum is a layer of the epidermis that contains cells involved in immune defense. The stratum lunula is a visible crescent-shaped area at the base of the nail plate and does not correspond to a specific layer of the epidermis.
