Verified step by step guidance

Step 1: Understand the concept of muscle tissue types. There are three main types of muscle tissue in the human body: skeletal muscle, cardiac muscle, and smooth muscle. Each type has distinct characteristics and functions.
Step 2: Learn about voluntary vs. involuntary control. Voluntary muscles are controlled consciously, while involuntary muscles function automatically without conscious control.
Step 3: Examine the characteristics of smooth muscle. Smooth muscle is found in the walls of hollow organs (e.g., intestines, blood vessels) and is under involuntary control, meaning it operates automatically.
Step 4: Examine the characteristics of cardiac muscle. Cardiac muscle is found in the heart and is also under involuntary control, as it contracts automatically to pump blood throughout the body.
Step 5: Compare skeletal muscle to the other types. Skeletal muscle is attached to bones and is under voluntary control, meaning it requires conscious effort to move. Therefore, skeletal muscle is not under involuntary control.
