The Sliding Filament Theory: How does a muscle contract?

WebThe sliding filament theory was first proposed by Andrew Huxley and Hugh Huxley in the 1950s, based on their observations of muscle fibers using electron microscopes. They discovered that muscles contain thin filaments made of actin and thick filaments made of myosin, and that these filaments overlap in a specific pattern to form a repeating unit … Web1 jul. 2024 · Huxley correctly identifies this structure with a sliding filament model in which “myosin” now becomes two proteins, actin (thin filaments) and myosin (thick filaments) which slide between each other as the muscle contracts and relaxes. tibialis anterior location and function
