Which layers of the epidermis are listed in the correct order from outer to inner?

The correct choice presents the layers of the epidermis in their proper order, moving from the outermost layer to the innermost layer. The epidermis consists of several distinct layers, and understanding their sequence is crucial in skincare and dermatology.

Starting with the outermost layer, we have the stratum corneum, which is composed of dead keratinized cells that provide a protective barrier against environmental damage, pathogens, and moisture loss. Beneath this is the stratum lucidum, which is found mainly in thick skin areas like the palms of the hands and soles of the feet, providing an additional layer of protection. Following is the stratum granulosum, where keratinocytes begin to lose their nuclei and start the process of keratinization, resulting in the accumulation of keratohyalin granules. Next, we have the stratum spinosum, characterized by polygonal keratinocytes that are interconnected by desmosomes, which provide strength and flexibility. Finally, the innermost layer, stratum basale, contains actively dividing cells (keratinocytes) that continuously produce new cells to replenish those lost at the skin's surface.

This choice correctly follows the anatomical and physiological order of the epidermal layers,
