Final answer:
The hypodermis is not exclusively made up of fat; it also includes areolar connective tissue, blood vessels, and nerves in addition to adipose tissue.
Step-by-step explanation:
The statement that the hypodermis is exclusively made up of fat is false. While the hypodermis does contain adipose tissue, which is fat-storing tissue made of adipocytes, it is not solely composed of this type of tissue.
This layer underneath the dermis serves several purposes, providing insulation, energy storage, and protection, but it also includes areolar connective tissue, rich in collagen and elastin, as well as a network of blood vessels and nerves. The hypodermis attaches the overlying skin to the bones and muscles, supporting the dermis and epidermis above it. Therefore, its composition is more complex than just fat.
