Final answer:
The false statement concerning the hypodermis is that it is a source of blood vessels in the epidermis; the epidermis is avascular and does not have its own blood supply.
Step-by-step explanation:
The question asks which statement concerning the hypodermis is false. The hypodermis is indeed mainly composed of adipose tissue, serving as insulation, energy storage, and a cushion for underlying organs, hence statements (a) and (b) are true. It does connect the skin to underlying muscles and bones, making statement (c) true. However, the hypodermis does not contain the source of blood vessels for the epidermis, as the epidermis is avascular, which means it does not contain blood vessels. Instead, the hypodermis contains its own blood vessels and nerve endings that supply the dermis. Therefore, statement (c), which states that the hypodermis is a source of blood vessels in the epidermis, is the false one.
