Which tissue forms a protective outer layer of the skin?

• A. Epithelial Tissue
• B. Connective Tissue
• C. Muscle Tissue
• D. Nervous Tissue

Answer: (A)

Epithelial tissue forms the protective outer layer. In the skin, the outermost layer, the epidermis, is made of stratified squamous epithelium. This arrangement provides a sturdy, waterproof barrier that guards against abrasion, pathogens, and water loss. The outermost cells become keratinized, forming the stratum corneum, which strengthens the barrier further. Deeper to the epidermis lies the dermis, which is connective tissue that supplies nutrients and support to the epithelium. Muscular and nervous tissues are present as well, but they reside below the protective surface and do not form the outer covering.
