Which system includes bones, muscles, tendons, and ligaments?

• A. Integumentary System
• B. Musculoskeletal System
• C. Cartilage
• D. Organ System

Answer: (B)

Movement and support come from an integrated network where bones form the framework, muscles generate force, tendons connect muscles to bones, and ligaments stabilize joints. This combined network is the musculoskeletal system, which explicitly includes those components and their roles in locomotion and posture. The integumentary system involves skin, hair, and nails, not bones or muscles. Cartilage is a connective tissue found within joints but isn’t a system by itself. An organ system is a broad term for a group of organs, not the specific collection of bones, muscles, tendons, and ligaments.
