Explain the Different Currents Underlying the Action Potential
The current is distinctively different in both its kinetics and pharmacology from the conventional calcium current described in single. The longitudinal current is determined by the difference in potential between the region where the impulse is at its peak and the region ahead normally resting. Untitled Document Outward currents are shown as positive and are hyperpolarizing. . Request PDF A model of the action potential and underlying membrane currents in a rabbit atrial cell We have developed a mathematical model of the rabbit atrial myocyte and have used it in an. Switch to Voltage Clamp. Underlying these action potentials are highly nonlinear voltage-dependent ionic conductances with varying biophysical properties. Full PDF Package Download Full PDF Package. For example at the resting potential potassium currents flow out of the nerve cell and act to hyperpolarize it. For long steady stimuli like the currents underlyin...
