Which of the following is NOT a function of the skeletal system?

• A. Temperature regulation
• B. Support
• C. Movement
• D. Protection

Answer: (A)

Understanding the functions of the skeletal system shows that bones provide the body’s framework, enable movement as levers with muscles, and protect vital organs. Temperature regulation, on the other hand, is handled by the skin and circulatory system—through sweating, blood flow changes, and insulation—rather than by bones. So, the option describing temperature regulation is not a skeletal function, while support, movement, and protection are. In short, the skeleton supports, protects, and enables motion, but temperature control comes from the skin and circulatory system.
