Slow Oscillations of Transmembrane Na und K Fluxes in Vascular Smooth Muscle

Abstract

Vascular smooth muscle possesses all of the properties of a rhythmic system (3). Spontaneous, rhythmic contractions of blood vessels occur, parallel to spikes and oscillations of the membrane potential. These phenomena must be based on corresponding ionic movements which have not yet been observed.
