What is the hypodermis?

The hypodermis, also known as the subcutaneous tissue, is the deepest layer of the skin and is composed of adipose tissue (fat), connective tissue, and blood vessels. It lies beneath the dermis and is responsible for providing insulation, storing energy, and protecting the body from external impacts and injuries. The hypodermis also helps to regulate body temperature and provides cushioning for the underlying organs and tissues.
