    There are three different kinds of muscle tissue: smooth muscle in the walls of the gut and blood vessels; cardiac muscle in the heart and skeletal muscle attached to the skeleton.

    • Tendons attach skeletal muscles to the skeleton.
    • Ligaments link bones together at a joint.
    • Skeletal muscles work in pairs known as antagonistic pairs. As one contracts the other in thepair relaxes.
    • Flexion is the movement that reduces the angle of a joint. Extension increases the angle of a joint.
