There are two types of muscle in the body. The Cardiac Muscle and the Skeletal Muscle. The skeletal muscle is made up of intrafusal and extrafusal fibers. The Muscle Belly is made up entirely of extrafusal fibers (even in the deepest parts). The intrafusal fibers are located throughout the muscle. The cardiac muscle is distinct from skeletal muscle, one of the main differences is the amount of mitochondria it has is increased, and so technically at the deepest part of cardiac muscle is mitochondria (but there are other components as well).
