[Pacemakers of visceral systems].
Autorhythmic contractions of smooth musculature in visceral systems appears as basic rhythm which is special for rhythmically contracting organs. These rhythms are founded on pacemaker excitation generated by interstitial cells of Cajal (ICC), ICC-like and atypical smooth muscle cells. Pacemaker excitation mechanism based on intracellular exchange of Ca2+ between endoplasmic reticulum depo and mitichondria. Interrelations between three different generations of ICC in gastrointestinal tract and between ICC-like and atypical smooth muscle cells are discussed. There are in this review some data on pacemaker and pacemaker-like activity in uterus, fallopian tube and prostate.
