Which layer lies beneath the dermis and provides insulation due to fat tissue?

• A. Epidermis
• B. Subcutaneous layer
• C. Dermis
• D. Stratum lucidum

Answer: (B)

The insulation comes from the fat-containing layer beneath the dermis, called the subcutaneous layer (often referred to as the hypodermis). This layer is primarily adipose tissue, which stores fat and helps keep body heat in, while also cushioning and anchoring the skin to underlying structures. The epidermis is the outer protective layer, and the dermis sits above the subcutaneous layer. Stratum lucidum is a thin layer within the epidermis, not a separate layer beneath the dermis.
