That depends entirely upon the receptor that norepinephrine activates.

Smooth Muscle Cells
Acetylcholine and norepinephrine both affect smooth muscle contraction. They stimulate contraction in some muscles and inhibits contraction in others.
It varies: In the somatic system (skeletal muscle) and parasympathetic branch of the autonomous nervous system (smooth & cardiac muscle) it is usually acetylcholine. In the sympathetic branch of the autonomous nervous system (smooth & cardiac muscle) it is usually norepinephrine (also called noradrenaline). There are exceptions, but this is the general rule.

yes it is.....
No, "smooth" muscle is a type of muscle.
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
