Answer 1

involuntary muscle that controls internal motions

Step-by-step explanation:

Smooth muscle tissue, also called unstriated muscle tissue or visceral muscle tissue, consists of mononucleated and elongated cells. This type of muscle can be found in the walls of hollow organs such as stomach, uterus, bladder, arteries, veins, blood vessels, etc.

Smooth muscle, like the striated cardiac muscle, presents involuntary movements and acts in the body in several ways, however controls the internal movements from where it is inserted.

Answer 2

Smooth muscle is an involuntary muscle that controls internal motions.

Smooth muscle cells are fusiform in shape and they have single nucleus. Smooth muscles are not striated muscles. We can see the smooth muscles in walls of internal organs such as bladder, organs of digestive system, organs of respiratory system, blood vessels and so on.
