Tendon

n. cord of fibrous tissue which connects a muscle to a bone or other part, sinew

A tendon (or sinew) is a tough band of fibrous connective tissue that connects muscle to bone and is built to withstand tension. Tendons are similar to ligaments except that ligaments join one bone to another. Tendons and muscles work together and can only exert a pulling force.
