Which sequence correctly describes the layers of skin starting from the outermost layer?

The sequence in option B accurately reflects the organization of the skin layers, beginning from the outermost. The epidermis is the top layer of the skin, acting as a protective barrier. Below the epidermis lies the basement membrane, which acts as a support layer that separates the epidermis from the dermis. The dermis is the thicker, deeper layer that contains connective tissues, blood vessels, and other structures. Finally, the subcutaneous tissue, which is not technically part of the skin but supports it, lies beneath the dermis, providing insulation and cushioning.

This correct sequence illustrates a clear understanding of skin anatomy and illustrates critical functions, such as protection, support, and nourishment. Understanding the structural relationship among these layers is essential for students in electrology and related fields to appreciate how treatments can affect skin health and integrity.
