When muscle cells are viewed under the microscope, one can see that they contain a striped pattern (striations). This pattern is formed by a series of basic units called sarcomeres that are arranged ...
Striated muscle contraction requires intricate interactions of microstructures. The classic textbook assumption that myosin filaments are compressed at the meshed Z-disc during striated muscle fibre ...
The sliding filament theory of muscle contraction has long provided a framework for understanding muscle biology and disease. In 1954, two teams showed that during shortening of striated muscle the ...
