What consists of five layers and is known as the cuticle portion of the skin?

  1. Epidermis

  2. Dermis

  3. Stratum corneum

  4. Stratum lucidum

The correct answer is: Stratum corneum

The correct answer is the stratum corneum, which is indeed known as the cuticle portion of the skin. This layer is the outermost section of the epidermis and is composed of dead skin cells that are continuously shed and replaced. The stratum corneum serves as a protective barrier, helping to prevent water loss and protect underlying tissues from pathogens and environmental damage. In addition to its role as a barrier, this layer is critical for the overall health of the skin, as it plays a vital role in maintaining hydration levels and providing a smooth surface. The five layers referenced may include the various sub-layers of the epidermis, culminating in the stratum corneum. Understanding the specific functions of the layers of the epidermis, particularly the stratum corneum, is essential for realizing how the skin offers protection and maintains homeostasis.
