Detailed explanation-1: -The I bands contain only thin (actin) filaments, whereas the A bands contain thick (myosin) filaments.
Detailed explanation-2: -Answer and Explanation: The protein that makes up the thick filaments is myosin. Thick filaments are one part of the sarcomere, the unit of contraction within muscle cells.
Detailed explanation-3: -Thin filaments (actin) and thick filaments (myosin) are present in almost every cell type. Thin filaments, also called microfilaments, are 5 to 8 nm in diameter.
Detailed explanation-4: -What Are Actin and Myosin? Actin and myosin are both proteins that are found in all types of muscle tissue. Myosin forms thick filaments (15 nm in diameter) and actin forms thinner filaments (7nm in diameter). Actin and myosin filaments work together to generate force.
