The fatty layer of the skin is called the subcutaneous layer or hypodermis. It is the deepest layer of tissue in the skin and is primarily composed of fat cells. The thickness of the fat layer can vary greatly from person to person, depending on their body mass and genetics.
The hypodermis serves several important functions:
- Insulation: It helps to keep the body warm by trapping heat.
- Protection: It cushions the body from impacts and protects the internal organs.
- Energy storage: Fat cells in the hypodermis store energy that can be used by the body when needed.
- Nutrient absorption: The hypodermis helps with the absorption of nutrients from the bloodstream.
- Connects the skin to the underlying muscles: The hypodermis anchors the skin to the underlying muscles and tissues.
The subcutaneous fat layer plays a significant role in overall health. It is involved in regulating body temperature, providing cushioning, and storing energy. The amount and distribution of subcutaneous fat can vary depending on factors like genetics, diet, and lifestyle.
