Quizplus · Accepted Answer

Smooth-muscle cells have the ability to contract independently, without nervous stimulation. This spontaneous contraction is known as myogenic activity and is regulated by the cells' own inherent pacemaker mechanism. However, nervous stimulation can increase or decrease the frequency and strength of contractions.
