Which involuntary muscle appears in only one place in the body?

1. Cardiac Muscle

2. Smooth Muscle

3. Skeletal Muscle

4. Digestive Muscle

The correct answer is: Cardiac Muscle

Cardiac muscle is the only involuntary muscle that appears in only one place in the body. This muscle is found exclusively in the heart, whereas other types of involuntary muscles, such as smooth muscle and skeletal muscle, can be found in various locations throughout the body. Digestive muscle is not a commonly used term and therefore is likely incorrect. Additionally, the digestive system contains both smooth and skeletal muscles, so they cannot be considered the only place where either of these muscles appear.
