Which of the following structures aids in the mobility of the skeleton?

Tendons are crucial for the mobility of the skeleton as they connect muscles to bones, allowing for movement when muscles contract. When a muscle fibers shorten, tendons transmit this force to the bones, facilitating the movement of joints and the entire skeleton. The strength and elasticity of tendons provide the necessary support and resilience, which are vital for a wide range of motions, from simple actions like walking to complex movements in sports.

While ligaments serve to connect bones to other bones and help stabilize joints, and cartilage provides cushioning at joint surfaces, tendons are specifically responsible for linking muscle action to skeletal movement. Fascia, on the other hand, is connective tissue that supports and surrounds muscles and other organs but does not directly contribute to the mobility of the skeleton in the same manner that tendons do.
