A membranous structure surrounding each myofibril which forms chambers (terminal cisternae) attached to t-tubules Contractile units of muscle Bundle of connective tissues at ends of skeletal muscles A structure formed by one T tubule and two terminal cisternae which concentrates and releases Ca2+. Layer which surrounds muscle fascicles and provides blood vessels and nerves to tissue Sheet of connective tissues at ends of muscles Strands of protein which reach from tips of thick filaments to the Z line and help to stabilize the thick and thin filaments Central nervous system (brain and spinal cord) Area around M line which contains only thick filaments Muscle fibers, connective tissues, nerves, blood vessels Area where thin and thick filaments converge Lengthwise subdivisions within muscle fiber which are made of myofilaments lines at centers of the I bands Layer which surrounds individual muscle cells and contains myosatellite cells (stem cells) that repair damage
