What is the hypodermis also known as?

The hypodermis is also referred to as the subcutaneous layer. This layer lies beneath the dermis of the skin and is primarily composed of loose connective tissue and fat cells. It serves several essential functions, including insulating the body, storing energy, and providing cushioning to protect underlying muscles and bones from external trauma. Additionally, the hypodermis contains larger blood vessels and nerves that supply the skin.

While the term "superficial fascia" can sometimes be used interchangeably with hypodermis in a broader anatomical context, it typically emphasizes the connective tissue aspect rather than the specific subcutaneous fat component. The muscularis layer is more associated with the muscular structure of certain organs and is not related to the skin. Lastly, although "adipose layer" describes the fat found within the hypodermis, it does not fully encompass the connective tissue and other components that characterize the subcutaneous layer more comprehensively.
