What makes up the Kinetic Chain?

• A. Circulatory, Digestive, Respiratory Systems
• B. Nervous, Skeletal, Muscle Systems
• C. Endocrine, Immune, Integumentary Systems
• D. Lymphatic System Only

Answer: (B)

Movement starts with a coordinated signal from the nervous system, muscles that respond by contracting, and the skeletal frame that bones and joints form to act as levers. The nervous system initiates the motor command, the muscles generate the force needed to move, and the skeleton provides the levers and joints that translate that force into action. Together, these three systems—nervous, skeletal, and muscular—constitute the chain by which movement is produced and transferred through the body. The other listed systems mostly support life functions like circulation, digestion, or immunity and don’t participate directly in transmitting movement in the way the neuromuscular-skeletal unit does.
