Might here in other classes, especially human physiology about absolute and relative refractory periods.
|
||||
|
||||
Refractory period we've been discussing here is mostly the absolute refractory period-- due to Na+ channel inactivation.
|
||||
|
||||
Relative refractory period is the transient hyperpolarization during the undershoot when potassium conductance is still greater than normal-- when K+ conductance returns to resting value the relative refractory period is over. Until this time, a greater secondary depolarizing stimulus will be required to reach AP threshold.
