Which statement describes this tissue's characteristic?

• A. This tissue contains striation
• B. This tissue is multinucleated
• C. This tissue is found in the lining of the digestive tract
• D. This tissue is under control of autonomic nervous system

Answer: (D)

Smooth muscle tissue is controlled by the autonomic nervous system, making it involuntary. This tissue forms the walls of hollow organs, including parts of the digestive tract, where its contractions help move contents along (peristalsis). It does not show striations like skeletal or cardiac muscle, and its cells are typically uninucleate rather than multinucleated. The lining of the digestive tract is epithelial, not smooth muscle, so the statement about autonomic control best captures its characteristic in this context.
