title: Comparison of NaCl-induced response across the tongue epithelium to that across other epithelia in the frog.
abstract: Electrical properties of the frog tongue epithelium were compared to those of skin and bladder, which have active sodium transport. During perfusion with Ringer solution, the potential difference across the tongue epithelium was negligible, unlike those of the skin and bladder. NaCl stimulation of the tongue epithelium produced a response with a polarity opposite to that of the skin and bladder. The response profile of the tongue epithelium except for the polarity resembled that of other tissues. In conclusion, the NaCl response of the tongue epithelium is independent of active sodium transport and instead occurs by passive transport, which may influence taste reception.
