Transverse velocities with zero gap-junctional coupling for extracellular volume fractions ranging up to 50% (A) with the junctional extracellular cleft width changing from $1.5\times {10}^{-6}$ cm to $15\times {10}^{-6}$ cm and sodium ion channels entirely on the ends of the cells and (B) with the junctional extracellular cleft width fixed at $1.5\times {10}^{-6}$ cm and different distributions of sodium ion channels.
