Understand the definitions: Voluntary muscles are those that can be consciously controlled, such as skeletal muscles. Involuntary muscles operate without conscious control, such as smooth and cardiac muscles.
Identify the types of muscle tissue: There are three main types of muscle tissue in the human body - skeletal, cardiac, and smooth.
Focus on cardiac muscle: Cardiac muscle is found in the heart and is responsible for pumping blood throughout the body.
Determine control mechanism: Cardiac muscle is controlled by the autonomic nervous system and intrinsic pacemaker cells, meaning it functions without conscious control.
Conclude the classification: Based on its control mechanism, cardiac muscle is classified as involuntary muscle tissue.
