What is the subcutaneous tissue composed of?

• A. Muscle tissue that moves hair.
• B. Fat that insulates and cushions the body.
• C. Water reservoir for hydration.
• D. Blood vessels that supply skin.

Answer: (B)

Subcutaneous tissue, also called the hypodermis, is mainly fat. This adipose tissue stores energy, provides insulation to help regulate body temperature, and cushions the body against bumps. It also helps anchor the skin to the underlying structures and contains larger blood vessels and nerves. The other descriptions reference different skin components—hair movement is controlled by tiny muscles in the dermis, and while the body uses water and has vessels there, the defining feature of this layer is its fat content.
