Thin and thick filaments are organized into repeating units called sarcomeres. Dark lines called Z-lines mark off the boundaries of each sarcomere. Thin filaments attach to the Z-lines at both ends of the sarcomere, while thick filaments are unattached. Each myofibril contains thousands of sarcomeres.
More specifically, the length of the thick and thin filaments do not change, but rather they slide over each other, bringing the thin filaments closer together in the middle and the thick filaments closer to the Z lines on the sides of the sarcomere. Each sarcomere shortens by about 1/3 of its resting length.
