WebThe I band is formed only of thin actin filaments. The region between consecutive Z lines is a single sarcomere. During muscle contraction, the I band is reduced in size as the overlap between the thick and thin filaments increases. The Z-lines come together, and so the sarcomere shortens as well. WebA sarcomere is the smallest contractile portion of a muscle. Myofibrils are composed of thick and thin filaments. Thick filaments are composed of the protein myosin; thin filaments are composed of the protein actin. Troponin and tropomyosin are regulatory proteins. Muscle contraction is described by the sliding filament model of contraction.
