Question

Quizplus · Accepted Answer

Sympathetic stimulation increases calcium influx, resulting in a stronger contraction. The sympathetic nervous system stimulates the release of epinephrine and norepinephrine, which activate beta-adrenergic receptors on the smooth muscle cells. This leads to an increase in calcium influx into the cells, which causes a stronger contraction.
