<h2>Region between 2 and 3</h2>
Explanation:
Muscles consists of two protein filaments:a thick filament which is made up of protein myosin whereas a thin filament is made up of protein actin
- During contraction,thin filaments slide past the thick filament resulting in shortening of sarcomere
- Myosin thick filaments grab on to the actin filaments by forming cross bridges
- The thick filaments pull the thin filaments past them making the sarcomere shorter
- The region between points 2 and 3 includes the area of overlap between thin and thick filaments
