Absolute & Relative refractory period


Absolute & Relative refractory period


ABSOLUTE Refractory Period – Any stimulus (Any strength) – NO RESPONSE (NO AP).

RELATIVE Refractory Period – From 1/3rd Repolarization till End of AP.

ONLY STUIMULUS OF MAXIMUM STRENGTH CAN PRODUCE RESPONSE.

During Depolarization  Na+ influx happens due to Voltage gated Na+ channels - With this in MIND GATE CONCEPT EVOLVED
