Store nutrient reserves such as glycogen, support soft tissues, maintain body temperature exterior collagen layer which separates muscle from surrounding tissues Layer which surrounds muscle fascicles and provides blood vessels and nerves to tissue Center of A band at midline of sarcomere mesodermal cells which fuse to produce skeletal muscle fibers. Bundle of connective tissues at ends of skeletal muscles Muscle fibers, connective tissues, nerves, blood vessels Lengthwise subdivisions within muscle fiber which are made of myofilaments A membranous structure surrounding each myofibril which forms chambers (terminal cisternae) attached to t-tubules Sheet of connective tissues at ends of muscles lines at centers of the I bands A structure formed by one T tubule and two terminal cisternae which concentrates and releases Ca2+. Central nervous system (brain and spinal cord) Area around M line which contains only thick filaments Contractile units of muscle cell membrane of a muscle fiber which surrounds the sarcoplasm Layer which surrounds individual muscle cells and contains myosatellite cells (stem cells) that repair damage Area where thin and thick filaments converge
