... decrease in negative transmembrane potential that is necessary to initiate an action potential (impulse). A decrease in negative transmembrane potential of 15 mV (e.g., from −70 to −55 mV) is necessary to reach the firing threshold; a ...
... decreases, approaching firing threshold for depolarization. When transmembrane potential is decreased by 15 mV from resting potential, a firing threshold is reached and rapid depolarization occurs. The newly depolarized segment sets up ...
... decreased diameter of sodium channels, which leads to inhibition of both sodium conductance and neural excitation (Fig. 1-12). The membrane expansion theory serves as a possible explanation for the local anesthetic activity of a drug ...
... decrease the permeability of ion channels to sodium ions (Na+). Local anesthetics selectively inhibit the peak permeability of sodium, whose value is normally about five to six times greater than the minimum necessary for impulse ...
... decreases local anesthetic effectiveness. Inadequate anesthesia results when local anesthetics are injected into inflamed or infected areas. The inflammatory process produces acidic products: The pH of normal tissue is 7.4; the pH of an ...
