Single-unit smooth muscle

Question

Quizplus · Accepted Answer

Single-unit smooth muscle contains an abundance of gap junctions which allows for synchronization of contraction, is self-excitable which means it can initiate contractions without input from the nervous system or hormones, is found in the walls of the digestive, reproductive, and urinary tracts as well as small blood vessels, and forms functional syncytia which means multiple cells work together as a coordinated unit. Therefore, all of the above characteristics apply to single-unit smooth muscle.
