What type of tissue is the subcutaneous layer primarily made from?

The subcutaneous layer, also known as the hypodermis, is primarily composed of adipose tissue. This layer of the skin serves several important functions. Adipose tissue acts as an insulating layer that helps to regulate body temperature by providing thermal insulation. It also serves as a cushion, protecting underlying muscles and organs from trauma. Additionally, the subcutaneous layer stores energy in the form of fat, which can be utilized by the body when needed.

In the context of skin anatomy, the subcutaneous layer is situated beneath the dermis and directly above the underlying tissues, allowing it to play a crucial role in supporting the overall structure of the skin while providing a connection to deeper tissues. The presence of blood vessels and nerves in this layer also facilitates the supply of nutrients and communication between the skin and the body.
