A skeletal - muscle fiber is a single muscle cell. Muscle fibers are the basic structural and functional units of skeletal muscle. They are long, cylindrical cells with multiple nuclei. The other options describe different muscle - related structures. A long, cylindrical structure made of several individual muscle cells is not the definition of a single fiber. A cord of connective tissue that connects a fascicle to a tendon is not a muscle fiber. A bundle of muscle cells is a fascicle, not a single fiber.
