A tendon is tough, but flexible, band of fibrous connective tissue. One end of the tendon connects to muscle. The other end the tendon connects to bone. Contraction of the muscle pulls on the tendon, causing the tendon to pull the bone. In this way, tendons play an important role in muscle control of the body.Tendons are made of parallel collagen fibers running the length of the tendon. These collagen fibers give the tendon its strength. Tendons grow into the bone creating a connection that is extremely strong and hard to break.he other end the tendon connects to bone.
