Verified step by step guidance

1. Step 1: Understand the three main types of muscle tissue in the human body: skeletal muscle, smooth muscle, and cardiac muscle.
2. Step 2: Recall that voluntary control means the muscle's movement is consciously controlled by the nervous system.
3. Step 3: Recognize that skeletal muscle is attached to bones and is responsible for body movements that you can consciously control.
4. Step 4: Note that smooth muscle is found in walls of internal organs and blood vessels and operates involuntarily, meaning it is not under conscious control.
5. Step 5: Understand that cardiac muscle, found only in the heart, also functions involuntarily to pump blood without conscious effort.
