Verified step by step guidance

Understand the characteristics of smooth muscle: Smooth muscle is a type of involuntary muscle tissue found in the walls of hollow organs such as the stomach, intestines, and blood vessels. It is responsible for movements like peristalsis and vasoconstriction.

Review the structural features of smooth muscle: Smooth muscle cells are spindle-shaped (elongated with tapered ends) and lack striations, which are the banded patterns seen in skeletal and cardiac muscle.

Differentiate between voluntary and involuntary control: Smooth muscle is under involuntary control, meaning it is regulated by the autonomic nervous system and not consciously controlled, unlike skeletal muscle.

Analyze the options provided: Compare each characteristic listed in the question to the known features of smooth muscle. Identify the one that does not align with the properties of smooth muscle.

Conclude that the correct answer is 'being under voluntary control,' as smooth muscle is involuntary and does not require conscious effort to function.
