What is the composition of subcutaneous tissue?

The composition of subcutaneous tissue primarily includes fat cells and fine fibers. This layer, also known as the hypodermis, serves several critical functions in the body. The presence of fat cells provides insulation, aiding in temperature regulation and serving as an energy reserve. Fine fibers, primarily collagen and elastin, impart flexibility and strength to the tissue, allowing it to support the upper layers of skin while also permitting movement.

Understanding the unique composition of subcutaneous tissue is essential for professionals in the field of aesthetics and skin care, as it plays a significant role in the overall appearance and health of the skin. This knowledge helps practitioners make informed decisions about treatments and therapies that affect the skin and underlying structures. The other options reflect components found in different tissues but do not accurately describe the primary constituents of subcutaneous tissue.
