WebOne sarcomere is the space between two consecutive Z discs. A myofibril is composed of many sarcomeres running along its length, and as the sarcomeres individually contract, the myofibrils and muscle cells shorten. Importantly, the actin and myosin fibers stay the same length by sliding past each other as the cell itself shortens.
