Question

9. In smooth muscle cells, a pacemaker potential differs from a graded potential because pacemaker potentials:1.
activate with the efflux of Na+ 2. always reach threshold 3.activate with the influx (entry) of Cl- 4.vary in size​

Answer 1

Answer:

Pacemaker potentials conduct electrotonically to smooth muscles cells (3, 14) and activate voltage-dependent conductances in these cells. Responses to pacemaker potentials recorded from smooth muscle cells have been termed slow waves.01-Mar-2005
