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