2) Which muscle is attached to a bone by tendons? A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to another bone, while tendons connect muscle to bone. The connective fibrous tissue is classified under "Connective Muscle" which includes tendons to bone, and fat and other soft padding.
