Another name for visceral muscle is smooth muscle, according to Inner Body. Unlike skeletal muscle, which is controlled voluntarily and enables the body to move, visceral muscle acts involuntarily to facilitate movement associated with digestion and other internal bodily processes.
The name "smooth muscle" comes from the visceral muscles' appearance, which is smooth and not striated like skeletal and cardiac muscles, according to faculty at Harford Community College. Visceral muscles are found in the digestive organs, including the stomach and the intestines, the blood vessels and the reproductive and urinary tract organs.
Visceral muscles are the weakest of the three types of muscles found in the human body, states Livescience.
