In comparing smooth and cardiac muscle, which one of the following best describes the differences between the two muscle types? Both lack muscle filaments, but cardiac muscle has sarcomeres. Cardiac muscle requires periods of relaxation, whereas smooth muscle is always in a state of partial contraction. Cardiac muscle multi nucleated cells, whereas smooth muscles uni nucleated cells. Smooth muscle is voluntary, whereas cardiac is involuntary.
