Detailed explanation-1: -The myosin filament is surrounded by six actin filaments and each actin filament is in turn surrounded by three myosin filaments. This arrangement of the actin and myosin filaments produce a striated appearance to the muscle. Therefore, the correct option is option C.
Detailed explanation-2: -There are Six actin filaments surround each myosin filament, and each actin filament is surrounded by three myosin filaments. This arrangement gives the muscles a striated appearance under magnification.
Detailed explanation-3: -The actin filaments surrounding each myosin filament vary in number from 6 to 11. The most frequent relationship is 9 to 1, followed by 10 to 1 and 8 to 1.
Detailed explanation-4: -Notice that in regions where the thick and thin filaments overlap, each thick filament is surrounded by six thin filaments and each thin filament is surrounded by three thick filaments. A sarcomere consists of more than just contractile and regulatory proteins.
Detailed explanation-5: -Actin rod =1m, ) myosin=1.5m 1Myosin filament & 1 Actin filament is surrounded by 3 Myosin filament.)
