An orthopedic physician specializes in which body system?

• A. Musculoskeletal system (bones & muscles)
• B. Nervous system
• C. Endocrine system
• D. Circulatory system

Answer: (A)

Orthopedic physicians specialize in the musculoskeletal system—the bones, muscles, joints, ligaments, tendons, and related tissues that enable movement and support. They treat conditions like fractures, arthritis, spine problems, sports injuries, and perform procedures such as joint replacements or fracture repairs. The other options point to different areas: the nervous system involves the brain, spinal cord, and nerves; the endocrine system involves glands and hormones; the circulatory system involves the heart and blood vessels.
