Alterations in posture, changes in range of motion, and slowed movement are related to which body system?

• A. Nervous
• B. Musculoskeletal
• C. Cardiovascular
• D. Endocrine

Answer: (B)

Posture, range of motion, and how quickly you move are governed by the musculoskeletal system—the bones, joints, and muscles together with their connective tissues. When aging or with strain, the spine may curve more (altered posture), joints can become stiffer (reduced ROM), and muscle strength and power can decline, leading to slower movement. These signs reflect changes in bones, joints, and surrounding muscles, which is the domain of the musculoskeletal system. The nervous system would more likely show issues with coordination or balance, the cardiovascular system with endurance and circulation, and the endocrine system with metabolic effects on bones and energy, but the specific combination described points to the musculoskeletal system.
