  2. Sliding filament theory - Wikipedia

    en.wikipedia.org/wiki/Sliding_filament_theory

    The sliding filament theory is a widely accepted explanation of the mechanism that underlies muscle contraction. [ 6 ] This model shows the four main and significant steps of the sliding filament theory as well as with a detailed visual.

    During this step ADP and Pi are released. In step 3 a new ATP binds to the myosin head and the cross bridge between the myosin and actin detach. In the last step the myosin head uses the new ATP to return to its erect state and is now ready to repeat the cycle.

  4. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    Sliding filament theory: A sarcomere in relaxed (above) and contracted (below) positions. The sliding filament theory describes a process used by muscles to contract. It is a cycle of repetitive events that cause a thin filament to slide over a thick filament and generate tension in the muscle. [22]

  6. Myofibril - Wikipedia

    en.wikipedia.org/wiki/Myofibril

    A diagram of the structure of a myofibril (consisting of many myofilaments in parallel, and sarcomeres in series) Sliding filament model of muscle contraction. The myosin heads form cross bridges with the actin myofilaments; this is where they carry out a 'rowing' action along the actin. When the muscle fibre is relaxed (before contraction ...

    Emmeline Jean Hanson FRS (14 November 1919 – 10 August 1973) was a biophysicist and zoologist known for her contributions to muscle research. [1] [2] [3] Hanson gained her PhD in zoology from Bedford College, University of London before spending the majority of her career at a biophysics research unit at King's College London, where she was a founder member, and later its second Head.

  8. Tropomyosin - Wikipedia

    en.wikipedia.org/wiki/Tropomyosin

    In effect, the thick filament moves or slides along the thin filament, resulting in muscle contraction. This process is known as the sliding filament model. The binding of the myosin heads to the muscle actin is a highly regulated process. The thin filament is made of actin, tropomyosin, and troponin.

    [9] [10] Thus the four people introduced what is called the sliding filament theory of muscle contractions. [11] Huxley synthesized his findings, and the work of colleagues, into a detailed description of muscle structure and how muscle contraction occurs and generates force that he published in 1957. [12]
