Smooth muscle

From Wikinfo

Smooth muscle is is a type of muscle found in the walls of hollow organs such as blood vessels, the gastrointestinal tract, the bladder, and the uterus. Smooth muscle is not under voluntary control.

Smooth muscle cells are joined to each other through gap junctions, and a wave of contraction is propagated slowly through the muscle.
