QUÉ SIGNIFICA ELECTROTONIC EN INGLÉS
Potencial electrotónico
En fisiología, electrotonus se refiere a la propagación pasiva de la carga dentro de una neurona. Pasivo significa que los cambios dependientes de la tensión en la conductancia de la membrana no contribuyen. Las neuronas y otras células excitables producen dos tipos de potencial eléctrico: ▪ Potencial electrotónico - un potencial local no propagado, resultante de un cambio local en la conductancia iónica. Cuando se extiende a lo largo de un tramo de membrana, se vuelve exponencialmente más pequeño. ▪ potencial de acción - un impulso propagado. Los potenciales electrotónicos representan cambios en el potencial de membrana de la neurona que no conducen a la generación de nueva corriente por potenciales de acción. Las neuronas que son pequeñas en relación con su longitud, como algunas neuronas en el cerebro tienen sólo potenciales electrotónicos; Las neuronas más largas utilizan potenciales electrotónicos para activar el potencial de acción. El potencial electrotónico viaja a través de propagación electrotónica, lo que equivale a la atracción de la oposición y la reflexión de iones de carga similar dentro de la célula. Los potenciales electrotónicos pueden sumar espacial o temporalmente.

ELECTROTONIC POTENTIAL AND LOCAL RESPONSE When a nerve fibre is
stimulated by subminimal or subthreshold stimuli the action potential is not
produced, but there do occur some changes in the resting membrane potential.
