Answer Choices:
Keratinized stratified epithelium
✦ The epidermis is composed of keratinized stratified squamous epithelium.
✦ This multilayered structure provides mechanical protection against abrasion, pathogens, and water loss.
✦ The outermost layer (stratum corneum) consists of dead keratinized cells that form a protective barrier.
✦ Keratinocytes in lower layers proliferate and migrate upward, becoming keratinized as they move outward.
✦ This specialization allows the skin to act as a durable external barrier while remaining flexible.
