What is the relationship between the thin filaments and thick filaments in a resting state myofibril?
  1. The thin filaments completely overlap the thick filaments
  2. The thin filaments do not overlap the thick filaments
  3. The thin filaments partially overlap the free ends of the thick filaments
  4. The thin filaments completely separate the thick filaments
