Search for Anisotropy in Specific Electrical Conductance of Ureteral Tissue as a Measure of Muscle-Fiber Structure
Electrical conductance is measured in pieces of ureteral tissue in two mutually perpendicular directions by means of a four-electrode technique. No anisotropy in conductance is found. It is concluded that there is no predominant fiber orientation. Passive tissue is a capacitance which, combined with the conductance, yields a value of a time constant which is too short to be a limiting factor in the propagation of peristaltic wave.
