What is the subcutaneous tissue also known as?

The subcutaneous tissue is also known as adipose tissue, which is primarily composed of fat cells. This layer lies beneath the dermis of the skin and serves several important functions. It acts as an insulator, helping to regulate body temperature by reducing heat loss. The adipose tissue also provides a cushioning effect, protecting underlying muscles and bones from external trauma. Additionally, it serves as an energy reserve, storing fat that the body can utilize when needed.

The other options refer to different types of tissues in the body. Connective tissue is a broad category that includes various types of tissues that support, bind, and protect other tissues and organs. Epithelial tissue covers body surfaces and lines cavities and organs. Muscle tissue is responsible for movement in the body. Therefore, the correct identification of the subcutaneous tissue as adipose is essential for understanding its role in the body's structure and function.
