  1. MUSCULAR SYSTEM POWER POINT • I. Muscular System -Protection, movement, joints, heat,etc.. • Muscle cells are elongated so called muscle _____ • Contraction due to microfilaments • Myo, mys, sarco refer to: ________________ • 3 types of muscle • Skeletal-attach to bones by____, multinucleated. • ___________ and ___________

  3. Connective Tissue Coverings: Endomysium surrounds each muscle fiber Epimysium surrounds entire skel muscle Perimysium surrounds a bundle of fibers (fascicle)

  4. Muscles composed of myofibrils that have light bands (actin) and dark bands (myosin) The sarcomere has thick ______ and thin _____ filaments Myosin has heads that allow it to attach to actin. These form cross bridges with actin during contraction.
