A tendon is a fibrous connective tissue that connects muscles to bones in the body. Tendons are composed primarily of collagen, which provides strength and flexibility, allowing them to withstand the high tensile forces generated when muscles contract. When a muscle contracts, the force is transmitted through the tendon to the bone, resulting in movement at the joint. Tendons can vary in thickness, length, and elasticity depending on their location in the body and the specific functions they perform.
