What tissue mainly composes the subcutaneous layer of the skin?

Muscle tissue
Adipose (fatty) tissue
Epithelial tissue
Connective tissue

The correct answer is: Adipose (fatty) tissue

The subcutaneous layer of the skin, also known as the hypodermis, is primarily composed of adipose tissue, which is a type of connective tissue that stores fat. This layer serves several important functions, including insulation to regulate body temperature, cushioning to protect underlying structures, and serving as an energy reserve. By maintaining a layer of fat beneath the dermis, the subcutaneous layer also aids in the mobility of the skin over underlying tissues and helps anchor the skin to various structures below, such as muscles and bones. While connective tissue does play a role in the composition of the subcutaneous layer, adipose tissue is a specific type of connective tissue that is particularly abundant in this area, making it the most relevant answer to the question. Other types of tissue, such as muscle or epithelial tissue, are not significant components of the subcutaneous layer, as muscle is found deeper in the body and epithelial tissue makes up the outermost layer of the skin (the epidermis).
