smooth mus·cle

one of the involuntary muscle fibers of the internal organs, blood vessels, and other body structures not under direct control of the will; contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei and a length of 20-200 mcm, or even longer in the pregnant uterus; although transverse striations are lacking, both thick and thin myofibrils occur; smooth muscle fibers are bound together into sheets or bundles by reticular fibers, and frequently elastic fiber nets are also abundant.

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.

(smūdh mŭs'ĕl)
One of the muscle fibers of the internal organs, blood vessels, hair follicles; contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei and a length from 20-200 mcm, or even longer in the pregnant uterus; although transverse striations are lacking, both thick and thin myofibrils occur; such fibers are bound together into sheets or bundles by reticular fibers, and frequently elastic fiber nets are also abundant.
