Central nervous system (brain and spinal cord) Strands of protein which reach from tips of thick filaments to the Z line and help to stabilize the thick and thin filaments Lengthwise subdivisions within muscle fiber which are made of myofilaments Center of A band at midline of sarcomere exterior collagen layer which separates muscle from surrounding tissues Layer which surrounds muscle fascicles and provides blood vessels and nerves to tissue Area where thin and thick filaments converge Bundle of connective tissues at ends of skeletal muscles Muscle fibers, connective tissues, nerves, blood vessels Sheet of connective tissues at ends of muscles Area around M line which contains only thick filaments lines at centers of the I bands Store nutrient reserves such as glycogen, support soft tissues, maintain body temperature mesodermal cells which fuse to produce skeletal muscle fibers. Layer which surrounds individual muscle cells and contains myosatellite cells (stem cells) that repair damage
