The subcutaneous tissue, also known as the hypodermis, lies below the epidermis and dermis. It is the deepest layer of the skin. The hypodermis consists of a network of fat and connective tissue that houses larger blood vessels and nerves, and is responsible for attaching the skin to the underlying bone and muscle. It serves many functions, including insulation, energy storage, and cushioning.
Additionally, this layer plays a crucial role in supplying blood vessels and nerves to the more superficial layers of the skin, particularly the dermis. This layer is essential for regulating temperature and providing protection to the body's internal organs.The subcutaneous tissue also contains nerves and blood vessels.
