WebOct 4, 2024 · myofilaments during contraction is called the sliding filament model of muscle contraction. During contraction, the actin myofilaments on each side of the sarcomere move into the H zone, shortening the sarcomere. However, the actin and myosin myofilament lengths are unchanged. 2. WebAccording to the sliding filament theory of muscle contraction, muscles shorten when: a. actin and myosin coil around each other; the tighter the coiling, the more contracted the muscle. b. adjacent cells slide past each other, but the individual cells stay the same length. c. actin filaments shorten, pulling the ends of the cell closer together.
