Question

Quizplus · Accepted Answer

Smooth muscle fibers and cardiac muscle fibers are both under involuntary control, meaning their activities are not consciously controlled by the individual. Smooth muscle is found in the walls of hollow organs like the intestines and blood vessels, while cardiac muscle is found in the heart. Both types of muscle operate without the need for conscious thought, contrasting with skeletal muscle, which is under voluntary control.
