Final answer:
The hypodermis is falsely claimed to be composed of tight connective tissue; it is actually made of loose areolar connective tissue and adipose tissue, serving as a connector, insulator, and cushion for the skin.
Step-by-step explanation:
The statement 'The hypodermis is composed of tight connective tissue' is false. Instead, the hypodermis, also known as the subcutaneous layer or superficial fascia, is composed of loose, areolar connective tissue and adipose tissue. Its primary functions are to connect the skin to underlying bones and muscles, store fat, provide insulation, and offer cushioning for the integument.
This layer is well-vascularized, aiding in thermoregulation and providing energy storage in the form of adipocytes, which are fat-storing cells within the adipose tissue.
