What is the name of the fatty tissue found below the dermis?

The fatty tissue found below the dermis is known as the subcutaneous layer. This layer plays a crucial role in providing insulation to the body, storing energy, and acting as a cushion to protect underlying structures such as muscles and bones from trauma. Additionally, the subcutaneous layer houses larger blood vessels and nerves that extend into the dermis, facilitating the exchange of nutrients and signaling between layers.

Understanding the importance of the subcutaneous layer highlights its function in overall skin health and body regulation. While the term "adipose layer" might refer to the fat within the subcutaneous layer, it is not the established anatomical name for that particular tissue layer. "Panniculus" is often used to describe a thick layer of subcutaneous fat in some contexts, but it is not the standard term for the layer itself. The "stratum corneum," meanwhile, refers to the outermost layer of the epidermis, which is not composed of fatty tissue at all.
