Verified step by step guidance1
Understand the structure of the epidermis, which is the outermost layer of the skin, composed of several sub-layers.
Identify the characteristics of each layer: Stratum basale is the deepest layer where cell division occurs; Stratum spinosum is above the basale and provides strength and flexibility; Stratum granulosum is where keratinization begins; Stratum corneum is the outermost layer composed of dead, keratinized cells.
Focus on the process of keratinization, where cells become filled with keratin protein, die, and form a tough, protective layer.
Recognize that the Stratum corneum is characterized by multiple layers of flattened, dead, keratinized cells, providing a barrier against environmental damage.
Conclude that the layer of the epidermis made of layers of elongated keratinized cells is the Stratum corneum.
