Detailed explanation-1: -A-band contains both actin and myosin. M-line and Z-line are in the middle of thick and thin filaments, respectively.
Detailed explanation-2: -Force in Smooth Muscle Arises from Ca2+ Activation of Actin–Myosin Interaction. Smooth muscles contain thick and thin filaments, composed predominantly of myosin and actin, respectively. However, their arrangement is quite different from the striated muscles.
Detailed explanation-3: -Structural arrangement of actin and myosin in A band is such that each actin filament is surrounded by 3 thick (myosin) filaments and each myosin filament is surrounded by 6 thin (actin) filaments.
