Definition & Meaning of "sinew"

What is "sinew"?

Sinew refers to a fibrous connective tissue that connects muscles to bones. It plays a vital role in the body's movement and mechanical function. Sinews are strong and flexible, allowing muscles to transmit force and generate movement by pulling on the bones they are attached to. They provide stability, support, and coordination during various physical activities, ranging from simple tasks to complex athletic movements. Sinews are made up of collagen fibers, which possess high tensile strength, enabling them to withstand the forces generated during muscle contractions. The health and integrity of sinews are essential for optimal musculoskeletal function and overall physical performance.
