Skeletal muscle is a voluntary muscle type that is composed of long muscle cells and fibers. They are directly controlled by yourself and are used for movement. It is the muscle that makes up all the more superficial musculature.
Smooth muscle is the muscle that is controlled involuntarily, meaning it doesn't act on an impulse but rather is constantly working. They compose organs such as the bladder, Large Intestines, and small intestines. Smooth muscle is fairly elastic and can stretch to accomadate contents.
Cardiac muscle is unique to the Heart. It is designed to continuously pump, on involuntary impulse. Its muscle cells share some characteristics with smooth and skeletal muscle.
