leiomy/o (5/12)

List item

leiomy/o is a combining form that refers to “smooth visceral muscle”.

Smooth (visceral) muscle fibers are found in the walls of hollow internal organs (including the liver, pancreas, and intestines), with the exception of the heart. Visceral muscle allows organs to contract and move substances. A visceral muscle is controlled by the brain’s unconscious part, making it an involuntary muscle.
