What is the major load-distributing structure of the musculoskeletal system?

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

Answer: (D)

The main idea is that weight and forces are carried by the skeleton. Bones form the rigid framework that bears body weight, distributes those forces through the joints, and channels them toward the ground. They are built to withstand compression, tension, and shear, and their arrangement as the skeleton provides the primary load-bearing pathway in the body. Muscles generate and transfer forces to move the limbs, with tendons transmitting those muscle forces to bones to create movement. Fascia surrounds and stabilizes muscles and other tissues and helps with local force transmission and tissue organization, but it does not serve as the body's major load-bearing structure.
