Detailed explanation-1: -Myofibrils are composed of long proteins including actin, myosin, and titin, and other proteins that hold them together. These proteins are organized into thick, thin, and elastic myofilaments, which repeat along the length of the myofibril in sections or units of contraction called sarcomeres.
Detailed explanation-2: –fascicles make up muscles, fibers (cells) make up fascicles, within fiber you have organelle packed with myofilaments and those are called myofibrils, myofibrils contain sarcomeres.
Detailed explanation-3: -A myofibril is a long cylindrical organelle found in muscle cells formed by two transverse filament systems: the thick and thin filaments.
Detailed explanation-4: -Myofibrils are composed of smaller structures called myofilaments.
