Indicate which statements are true. Correct all false statements by changing the underlined words.
__________ The surface cells of the epidermis of the skin are alive.

검증된 단계별 안내

Understand the structure of the epidermis: The epidermis is the outermost layer of the skin composed of multiple layers of cells.
Recall that the surface cells of the epidermis are part of the stratum corneum, which consists of dead, flattened cells filled with keratin.
Identify that the statement 'The surface cells of the epidermis of the skin are alive' is false because these surface cells are actually dead.
Correct the statement by replacing the underlined word 'alive' with 'dead' to accurately describe the surface cells of the epidermis.
Summarize: The surface cells of the epidermis of the skin are dead, not alive, as they form a protective barrier composed of keratinized cells.

Structure and Function of the Epidermis

The epidermis is the outermost layer of the skin composed mainly of keratinized cells. Its surface cells, primarily in the stratum corneum, are dead and serve as a protective barrier against environmental damage and water loss.

Keratinization Process

Keratinization is the process by which epidermal cells produce keratin, lose their nuclei, and die as they move toward the skin surface. This creates a tough, dead cell layer that protects underlying living cells.

Cell Viability in Skin Layers

Only the deeper layers of the epidermis, such as the stratum basale and stratum spinosum, contain living cells that divide and differentiate. Surface epidermal cells are dead, lacking nuclei and metabolic activity.
