body movement

Body movement results from the coordinated actions of muscles, bones, joints, and nerves. Muscles contract and relax to generate force, which is transmitted through tendons to bones, causing them to move at joints. The nervous system controls these signals, enabling smooth and purposeful motion. Movements can be voluntary, like walking or reaching, or involuntary, like heartbeat or reflexes. Proper movement depends on muscle strength, joint flexibility, and nerve function, working together to facilitate daily activities, maintain posture, and support overall physical health.
