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.
将青蛙舌上皮的电特性与具有活跃钠转运功能的皮肤和膀胱的电特性进行了比较。在用林格溶液灌注期间,舌上皮两侧的电位差可忽略不计,这与皮肤和膀胱不同。用氯化钠刺激舌上皮会产生与皮肤和膀胱相反极性的反应。除了极性外,舌上皮的反应特征与其他组织相似。总之,舌上皮对氯化钠的反应独立于活跃的钠转运,而是通过被动转运发生,这可能会影响味觉感受。
