Catelectrotonus altered state of a nerve or other excitable tissue that develops in the region of the cathode when a constant current passes through the tissue. The permeability of the cell membrane and the bioelectric potential change, and the irritability of the tissue is increased. Opposite changes occur in the region of the anode (anelectrotonus). catelectrotonusenUK
cat·e·lec·trot·o·nus (kat'ē-lek-trot'ō-nŭs), The changes in excitability and conductivity in a nerve or muscle in the neighborhood of the cathode during the passage of a constant electric current. [cathode + electrotonus] catelectrotonus (kăt″ē-lĕk-trŏt′ō-nŭs) [″ + elektron, amber, + tonos, tension] The increased excitability produced in a nerve or muscle in the region near the cathode during the passage of an electric current. |
