Final answer:
The hypodermis is the part of the skin that contains adipose tissue, which insulates the body, stores energy, and provides cushioning. It contains fat-storing cells known as adipocytes and connects the skin to the underlying fascia.
Step-by-step explanation:
The part of the skin that has adipose tissue to help insulate the body is the hypodermis. This layer is also known as the subcutaneous layer or superficial fascia. Composed predominantly of adipose tissue, it serves several critical functions:
- It acts as a storage area for fat, which is held in cells known as adipocytes.
- The stored fat works as an energy reserve.
- It insulates the body, helping to conserve heat and protect against cold temperatures.
- It serves as a protective cushion for underlying bones and muscles, reducing the impact of trauma.
Besides insulation and protection, the hypodermis connects the skin to the underlying fascia of bones and muscles and contains a network of blood vessels and nerves that support the overlying dermis and epidermis.
