Hipodermisë

Hipodermisë, also known as the subcutaneous tissue, is the deepest layer of the skin. It lies directly beneath the dermis, the layer above it. This layer is primarily composed of loose connective tissue and adipose tissue, which is fat. The main functions of the hipodermis include insulation, energy storage, and cushioning for the body.

The adipose tissue within the hipodermis acts as an insulator, helping to regulate body temperature by preventing heat loss. It also serves as a vital energy reserve, storing calories that the body can access when needed. Furthermore, the fatty nature of the hipodermis provides a protective padding for underlying muscles, bones, and organs, absorbing shock and preventing injury from impacts.

Blood vessels and nerves also traverse the hipodermis, supplying nutrients and sensory information to the overlying skin layers. In some areas of the body, the hipodermis can be quite thick, contributing significantly to a person's body mass and overall shape. It plays a crucial role in maintaining the structural integrity and physiological functions of the integumentary system. The appearance and thickness of the hipodermis can vary greatly among individuals due to factors such as genetics, diet, and lifestyle.
