Ihonalaisrasva

Ihonalaisrasva, also known as subcutaneous fat, is the layer of adipose tissue located directly beneath the skin. It is the largest of the three main types of fat in the human body, with visceral fat and intramuscular fat being the other two. This fatty tissue plays a crucial role in insulation, helping to maintain body temperature and protect vital organs from impact and shock.

The composition of ihonalaisrasva includes adipocytes, which are specialized cells that store energy in the form of triglycerides. When the body requires energy, these triglycerides are broken down and released into the bloodstream. Ihonalaisrasva also contains blood vessels, nerves, and connective tissue.

The amount and distribution of subcutaneous fat vary significantly among individuals, influenced by factors such as genetics, diet, physical activity levels, and hormonal changes. While a certain amount of subcutaneous fat is essential for health, excessive accumulation can contribute to obesity and associated health risks, including type 2 diabetes, cardiovascular disease, and certain types of cancer. Conversely, a severe lack of subcutaneous fat can impair insulation, reduce energy reserves, and lead to nutritional deficiencies. It is a dynamic tissue that responds to changes in energy balance, increasing when energy intake exceeds expenditure and decreasing when energy expenditure exceeds intake.
