    1. Chapter 6 The Muscular System

    2. The essential function of a muscle is to shorten or contract As a result of this ability, muscles are responsible for almost all body movement and can be viewed as the “machines of the body”

    3. Overview of Muscle Tissues

    4. Muscle Types - Three Skeletal Cardiac Smooth

    5. The 3 Types of Muscle Tissue differ in: Cell structure Body location How they are stimulated to contract

    6. The three types of muscle tissue are similar because: All muscle cells are elongated – called muscle fibers The ability of muscle to shorten or contract depends on 2 types of myofilaments (part of the cytoskeleton)

    7. Skeletal Muscle Fibers are packaged into skeletal muscles that attach to the skeleton Cigar-shaped Multinucleate (many nuclei) Largest of the muscle fibers

    8. Striated muscle (appear striped) Voluntary muscle (conscious control) Form smoother contours of the body

    9. Key words to think of for skeletal muscle: Skeletal, striated, voluntary

    10. Skeletal muscles are very fragile, but they are capable of exerting tremendous power. They are able to do this because: thousands of fibers are bundled together with connective tissue – these bundles are then bundled together

    11. Tendons Attach muscle to bone
