Central nervous system (brain and spinal cord) lines at centers of the I bands Contractile units of muscle Area where thin and thick filaments converge transmit action potentials through the cell and help the muscle fiber to contract simultaneously. mesodermal cells which fuse to produce skeletal muscle fibers. Muscle fibers, connective tissues, nerves, blood vessels Store nutrient reserves such as glycogen, support soft tissues, maintain body temperature Sheet of connective tissues at ends of muscles exterior collagen layer which separates muscle from surrounding tissues Lengthwise subdivisions within muscle fiber which are made of myofilaments
