CE ÎNSEAMNĂ REPOLARIZATION ÎN ENGLEZĂ?
repolarizarea
În neuroștiință, repolarizarea se referă la modificarea potențialului membranei care returnează potențialul membranei la o valoare negativă după ce faza de depolarizare a unui potențial de acțiune tocmai a schimbat anterior potențialul membranei la o valoare pozitivă; faza de repolarizare returnează, de obicei, potențialul membranei înapoi la potențialul membranei de repaus. Repolarizarea rezultă din mișcarea ionilor de potasiu încărcați pozitiv din celulă. În mod tipic, faza de repolarizare a unui potențial de acțiune are ca rezultat hiperpolarizarea, obținerea unui potențial de membrană mai negativ decât potențialul de repaus. Repolarizarea durează de obicei câteva milisecunde.
Definiția repolarization în dicționarul Engleză
Definiția repolarizării în dicționar este actul sau procesul de polarizare din nou, o polarizare reînnoită, restaurarea polarizării.
