Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, which are the basic functional units of the muscle fiber.
These cells are made of actin and myosin fibers repeated as a sacromere. Therefore skeletal muscle cells are long, cylindrical, multinucleated cells made of actin and myosin myofibers. They come together to create the fibers which make up tissues such as skeletal muscle tissue.+ 5 others found this useful.aking the world better, one answer at a time.
