Which of the following best describes the characteristics of smooth muscle?

The characteristics of smooth muscle are accurately described as involuntary, non-striated, and located in the walls of hollow organs. This type of muscle is responsible for various automatic processes in the body, such as the movement of food through the digestive tract, regulation of blood vessel diameter, and contraction of the bladder.

Smooth muscle fibers are not under conscious control, which differentiates them from skeletal muscles that are striated and voluntary. Additionally, smooth muscle lacks the visible striations found in skeletal and cardiac muscle, reflecting its unique structure and function. It is specifically found in the walls of hollow organs, such as the intestines, blood vessels, and the uterus, where it aids in involuntary movements necessary for bodily functions. Understanding these characteristics is crucial for differentiating smooth muscle from other types of muscle tissue in the human body.
