Abstract
There is a subpopulation of cells in the rabbit urethra differing in their morphology and electrophysiology from the bulk smooth cells. They are non-contractile but capable of generating rhythmic depolarizations, which can spread to neighboring smooth muscle. Possible mechanisms of such a pacemaker activity are discussed, with special attention to Ca2+ events.
