Verified step by step guidance1
Understand the characteristics of smooth muscle tissue: Smooth muscle tissue is found in the walls of hollow organs such as the intestines, blood vessels, and bladder. It is responsible for involuntary movements like peristalsis and vasoconstriction.
Compare smooth muscle tissue to other types of muscle tissue: Skeletal muscle is striated and voluntary, cardiac muscle is striated and involuntary, and smooth muscle is non-striated and involuntary.
Focus on the term 'non-striated': Smooth muscle tissue lacks the visible striations (banding patterns) seen in skeletal and cardiac muscle under a microscope.
Focus on the term 'involuntary': Smooth muscle tissue is controlled by the autonomic nervous system, meaning its actions are not consciously controlled.
Match the description to the correct answer: Based on the characteristics of smooth muscle tissue, identify the option that states 'It is non-striated and involuntary.'
