Subcutaneous layers or adipose tissues are the fat depositing layers found just below the skin or between internal organs. They reduce heat loss from the body and act as a good insulator. Animals of colder regions and fishes of cold water have a thicker layer of subcutaneous fat to retain heat in their body and thus maintaining body temperature. The thicker the layer of subcutaneous fat, the lesser will be the heat loss from the body.
Subcutaneous fat has five main functions.
- It’s the one way that your body stores energy.
- It functions as padding to protect your muscles and bones from the impact of hits or falls.
- It serves as a passageway for nerves and blood vessels between your skin and your muscles.
- It insulates your body, helping it regulate temperature.
- It attaches the dermis to the muscles and bones with its special connecting tissue.
