Smooth muscle is sometimes called visceral muscle because d) it is found in organs. Smooth muscle fibers are primarily located in the walls of hollow organs such as the intestines, bladder, and blood vessels. Unlike skeletal muscle, which has a striated appearance and is under voluntary control, smooth muscle is non-striated and operates involuntarily. This means it functions automatically, regulating bodily processes such as digestion and circulation without the need for conscious thought.
In summary, the term ‘visceral’ refers to the internal organs, reinforcing the relationship between smooth muscle and the organs in which it is located.
