Which structure is responsible for all types of movement?

• A. Nerves
• B. Bones
• C. Muscles
• D. Tendons

Answer: (C)

Movement is produced by muscle contraction. Muscles actively shorten to generate force, pulling on bones through tendons and across joints to create motion. Bones provide the levers and joints the pivot points, while tendons transmit the force from muscle to bone. Nerves control when muscles contract, but don’t produce the movement themselves, and while cardiac and smooth muscles move substances inside the body, the active force behind motion in limbs and body parts comes from skeletal muscle contractions. For this reason, muscles are the structure responsible for all types of movement.
