Question

Quizplus · Accepted Answer

Both multiunit and single-unit smooth muscles are under the motor control of the autonomic nervous system. However, the type of control may differ between the two types of smooth muscle. Multiunit smooth muscle is usually innervated by the sympathetic nervous system and responds to nerve impulses in a graded manner, while single-unit smooth muscle is often innervated by the parasympathetic nervous system and responds as a synchronized unit.
