Solution
The correct order of the 5 layers of thick skin from superficial to deep is:
Stratum Corneum
Stratum Lucidum
Stratum Granulosum
Stratum Spinosum
Stratum Basale (Germinativum)
Explanation:
Stratum Corneum: This is the outermost layer of the skin, consisting of dead keratinized cells that provide a protective barrier.
Stratum Lucidum: This layer is found only in thick skin, such as the palms of the hands and soles of the feet. It is a thin, clear layer of dead skin cells.
Stratum Granulosum: This layer contains keratinocytes that are undergoing a process of keratinization, where they become more flattened and filled with keratin.
Stratum Spinosum: This layer provides strength and flexibility to the skin. It contains keratinocytes that are connected by desmosomes, giving them a spiny appearance.
Stratum Basale (Germinativum): This is the deepest layer of the epidermis, where cell division occurs. It contains basal cells that continually divide to produce new keratinocytes.
In summary, the order from superficial to deep is Stratum Corneum, Stratum Lucidum, Stratum Granulosum, Stratum Spinosum, and Stratum Basale.
