What is the hypodermis also known as?

The hypodermis is commonly referred to as subcutaneous tissue. This layer of tissue lies beneath the dermis and primarily consists of fat and connective tissue, which serves several important functions. It acts as an insulator to help regulate body temperature, provides cushioning to protect underlying structures, and serves as an energy reserve. Additionally, the hypodermis anchors the skin to the underlying tissues and organs, allowing for flexibility and movement.

While terms like superficial fascia may also describe components of the hypodermis relating to the fascia surrounding muscles, subcutaneous tissue is the most direct and widely recognized term for this layer in the context of skin anatomy.
