The Skeletal Muscle Sarcomere Contraction Model

$365.00 $445.00

The skeletal muscle sarcomere contraction model displays a sarcomere of skeletal muscle. On one side, it shows the banding pattern of a skeletal muscle sarcomere under a light microscope, including the light band (I band), dark band (A band), H band, M line, and Z line. On the other side, it illustrates the thick and thin filaments, reflecting their distribution in the sarcomere with a three-dimensional structure. The thick filaments are located in the A band, while the thin filaments are situated in the I band and extend into the A band near the H band. Around one thick filament, six thin filaments are arranged in a hexagonal pattern, and around one thin filament, three thick filaments are arranged in a triangular pattern. A sarcomere consists of half an I band + an A band + half an I band. During muscle fiber contraction, the thin filaments slide between the thick filaments, and under a light microscope, the H band disappears while the I band narrows.
