smooth muscle

n.
Muscle tissue that contracts without conscious control, having the form of thin layers or sheets made up of spindle-shaped, unstriated cells with single nuclei and found in the walls of the internal organs, such as the stomach, intestine, bladder, and blood vessels, excluding the heart.

smooth muscle

n
(Anatomy) muscle that is capable of slow rhythmic involuntary contractions: occurs in the walls of the blood vessels, alimentary canal, etc. Compare striped muscle
[so called because there is no cross-banding on the muscle]

smooth′ mus′cle


n.
involuntary muscle tissue in the walls of viscera and blood vessels, consisting of nonstriated, spindle-shaped cells.

smooth muscle

Involuntary muscle without the striated fibers of skeletal muscle. It automatically operates internal organs such as the stomach, bladder, and blood vessels.
