sarcolemmas การใช้

• Muscular dystrophy is distinct from atrophy because it affects the Sarcolemma.
• Pressed against the inside of the sarcolemma are the unusual flattened myonuclei.
• Satellite cells are described as quiescent myoblasts and neighbor muscle fiber sarcolemma.
• This initiates an impulse that travels across the sarcolemma.
• Also, the breakdown of the sarcolemma causes additional calcium to enter the cytosol.
• The cell membrane is called the sarcolemma with the cytoplasm known as the sarcoplasm.
• CD97 is expressed at the sarcoplasmic reticulum and the peripheral sarcolemma in skeletal muscle.
• The sarcolemma ( membrane ) from adjacent cells bind together at the intercalated discs.
• The DPC localizes to the sarcolemma and its disruption is associated with various forms of muscular dystrophy.
• The purpose is to reduce the mechanical force on the sarcolemma as a result of muscle contraction.
• In normal muscle cells, utrophin is located at the differentiation, utrophin is found at the sarcolemma.
• The sarcolemma generally maintains the same function in muscle cells as the plasma membrane does in other eukaryote cells.
• Another group of cells, the myosatellite cells are found between the basement membrane and the sarcolemma of muscle fibers.
• In myocytes, sarcomeres adhere to the sarcolemma via costameres, which align at Z-discs in striated muscle cells.
• Dystrophin links actin in the cytoskeleton and dystroglycans of the muscle cell plasma membrane, known as the sarcolemma ( extracellular ).
• When complexes of actin and myosin contract, force is transduced to the sarcolemma through intermediate filaments attaching to such dense bands.
• This switches off voltage-gated calcium ion channels, preventing calcium flux across the sarcolemma and activation of the contractile apparatus.
• Therefore, it is one of the features of the sarcolemma which helps to couple the sarcomere to the extracellular connective tissue as some experiments have shown.
• Epsilon sarcoglycan itself is part of the dystrophin-associated protein ( DAP ) complex that binds the sarcolemma of muscle cells to the extracellular connective tissue.
• The sarcolemma is the cell membrane of a nuclei; this multinuclear condition results from multiple myoblasts fusing to produce each muscle fiber, where each myoblast contributes one nucleus.
