Which of the following lists the layers of the epidermis in order from deepest to most superficial?

• A. Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum
• B. Stratum spinosum, stratum basale, stratum granulosum, stratum corneum, stratum lucidum
• C. Stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale
• D. Stratum granulosum, stratum spinosum, stratum basale, stratum corneum, stratum lucidum

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the structure of the epidermis, which is the outermost layer of the skin. It consists of several layers of cells that are organized from the deepest (closest to the dermis) to the most superficial (exposed to the environment).
2. Step 2: Learn the names and functions of the layers of the epidermis. These layers, in order from deepest to most superficial, are: Stratum basale (responsible for cell division and regeneration), Stratum spinosum (provides strength and flexibility), Stratum granulosum (involved in keratinization), Stratum lucidum (found only in thick skin, such as palms and soles), and Stratum corneum (composed of dead cells that form a protective barrier).
3. Step 3: Recognize that the correct order of the layers is based on their anatomical position. The deepest layer is the Stratum basale, and the most superficial layer is the Stratum corneum.
4. Step 4: Compare the provided answer choices to the correct order of the layers. The correct sequence should match the anatomical arrangement: Stratum basale, Stratum spinosum, Stratum granulosum, Stratum lucidum, Stratum corneum.
5. Step 5: Eliminate incorrect options by identifying sequences that do not follow the proper anatomical order. Select the answer choice that accurately lists the layers from deepest to most superficial.
