The epidermis of thick skin ranges between ______ millimeters thick.

• A. 2.5 to 3.0
• B. 0.4 to 0.6
• C. 1.0 to 2.0
• D. 0.01 to 0.05

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the structure of the epidermis in thick skin. The epidermis is the outermost layer of the skin, and in thick skin (found on the palms of the hands and soles of the feet), it is significantly thicker compared to thin skin due to the presence of additional layers like the stratum lucidum.
2. Step 2: Recall the typical thickness of the epidermis in thick skin. Thick skin is specialized for areas subject to high friction and pressure, and its epidermis typically ranges between 0.4 to 0.6 millimeters thick.
3. Step 3: Compare the given options to the known range of epidermal thickness in thick skin. The options provided are: 2.5 to 3.0, 0.4 to 0.6, 1.0 to 2.0, and 0.01 to 0.05 millimeters.
4. Step 4: Eliminate options that are outside the typical range of 0.4 to 0.6 millimeters. For example, 2.5 to 3.0 millimeters is too thick, and 0.01 to 0.05 millimeters is too thin for the epidermis of thick skin.
5. Step 5: Identify the correct answer as the range that matches the known thickness of the epidermis in thick skin, which is 0.4 to 0.6 millimeters.
