The cardiac muscle
voluntary is muscles you choose to move, whereas involuntary are muscles that move without your will. an involuntary muscle wouuld be your heart and that it pumps blood, which is a cardiac muscle, a voluntary muscle is like you moving your hand up and down, and that is a skeletal muscle. its important because if you had to think to make your heart pump blood, you would probably die in your sleep. Also, its important for a skeletal muscle to be voluntary, because if it wasnt you cant ever control it, and it moves by itself.
The study of muscle is very important in the animals in a variety of ways from the way the animal protects itself to the way the animal feeds.
