There more thin filaments than thick filaments in smooth muscle. The ratio is of the thin to thick filaments in the smooth muscle is approximately 15:1.
True!
Striated muscle appears stripped due to the parallel alignment of many muscle fibers side to side with their sarcomeres lined up. The striations across each cell are caused by the overlap of the contractile proteins actin and myosin. Actin is the main protein of thin filaments and myosin is in the thick filaments. When actin and myosin are overlapped the darkest band appears( A band), when only actin is present a lighter band, is seen (I band).
thin filaments
Actin filaments
thick and thin bands (lines) of filaments.
Actin Filaments
The structure of muscle filaments - View diagram of the structure of muscle ... These two types of filament have different structures that enable then to work together. ... Thick filaments are formed from a protein called myosin which has important ...muscle filaments cause muscles to contract,
Interactions between actin and myosin filaments of the sarcomere are responsible for muscle contractions. The I bands contain only thin (actin) filaments, whereas the A bands contain thick (myosin) filaments.
ATP
Thick filaments are made of the protein myosin and thin filaments are made of the protein actin. Myosin and actin filaments are arranged to form and overlapping pattern which gives muscle tissue its striated appearance.
