What term best describes the combination of the muscular and skeletal systems?

• A. Nervous System
• B. Circulatory System
• C. Musculoskeletal System
• D. Endocrine System

Answer: (C)

Movement and posture arise from the musculoskeletal system, a combined framework of bones and muscles that work together. Bones provide the rigid framework and act as levers, joints allow movement, and muscles attach to bone surfaces (via tendons) and generate force by contracting to move the skeleton. This collaboration enables walking, jumping, and lifting, as well as maintaining balance and posture. Because it directly links muscular force with the skeletal structure to produce motion, the term that best describes this combined system is the musculoskeletal system. The other systems—nervous, circulatory, and endocrine—support movement in different ways (coordination, blood flow, hormone regulation) but do not describe the coordinated pair of muscles and bones as a single functional unit.
