What is the subcutaneous layer of the skin composed of?

• A. Fat tissue for insulation and cushioning
• B. Muscle tissue
• C. Water and minerals
• D. Tightly packed connective tissue

Answer: (A)

The subcutaneous layer, or hypodermis, is primarily made up of fat tissue (adipose tissue). This fat provides insulation to help regulate body temperature, cushions and protects underlying structures from impacts, and serves as an energy reserve. The layer also contains loose connective tissue and blood vessels that support the skin. Since fat is the main component, descriptions involving muscle tissue, water and minerals, or tightly packed connective tissue don’t describe this layer.
