Instead of a calcium trigger which sets off a contraction reaction, smooth muscle has more of a throttle, like in a car. Since there was always available ATP, the myosin uses it to quickly contract the cell. made of discrete bundles of cells, few or no gap junctional bridges, DENSELY innervated fibers contracting only to RESPONSE to innervation, funtional similarities to skeletal m., in walls of LARGE arteries airways of lungs, vas deferens, arrector pilli of hair, ciliary muscle that adjust lens & iris of the eye, in walls of SMALL arteries, hollw organs (uterus, ureters, bronchi, GI track (gut), endings of postganglionic autonomic neurons, diffuse junctions w/ underlying smooth muscle fibers.
