What is the outer protective layer of the skin called?

• A. Dermis
• B. Epidermis
• C. Hypodermis
• D. Stratum corneum

Answer: (B)

The epidermis is the outer protective layer of the skin. It forms the surface that shields against pathogens, chemicals, and water loss, and it sits atop the dermis. The epidermis itself has several sublayers, with the very outermost part being the stratum corneum, which helps seal moisture. Beneath the epidermis lies the dermis, providing strength and elasticity, and deeper still is the hypodermis, which stores fat. So, while the stratum corneum is the outermost sublayer, the overall outer protective layer is the epidermis.
