Bundle of connective tissues at ends of skeletal muscles 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 Layer which surrounds individual muscle cells and contains myosatellite cells (stem cells) that repair damage Strands of protein which reach from tips of thick filaments to the Z line and help to stabilize the thick and thin filaments Center of A band at midline of sarcomere
