Breakdown the Problem

1. Identify the layers of the epidermis relevant to thick and thin skin.
2. Determine which layer is present only in thick skin.

Relevant Concepts

• The epidermis has multiple layers known as stratum, including stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.
• Thick skin is typically found in areas subject to abrasion (e.g., palms and soles) and contains an additional layer compared to thin skin.

Analysis and Detail

1. Stratum Corneum: Present in both thick and thin skin as the outermost layer.
2. Stratum Lucidum: A clear layer found only in thick skin.
3. Stratum Granulosum, Stratum Spinosum, and Stratum Basale: Present in both types of skin.

Verify and Summarize

The stratum lucidum is specifically found in thick skin and not in thin skin.

Final Answer

The correct answer is stratum lucidum.
