Which muscle tissue is found in hollow organs and lacks striations?

• A. Skeletal muscle tissue
• B. Cardiac muscle tissue
• C. Smooth muscle tissue
• D. Nervous tissue

Answer: (C)

Muscle tissue types differ in appearance, control, and where they are located. Smooth muscle is non-striated and made of spindle-shaped cells, which gives it a smooth look under a microscope. It lines hollow organs such as the stomach, intestines, bladder, and blood vessels, where it contracts to move contents along and regulate vessel diameter. These contractions are involuntary and typically slower than those of other muscle types. The other options don’t fit because skeletal muscle is striated and voluntary, attached to bones for body movement; cardiac muscle is striated and involuntary but is found only in the heart; nervous tissue is not muscle tissue at all.
