Know absolute and relative refractory period
relative refractory membrane response
MEMBRANE CAN RESPOND TO FURTHER STIMULATION IF STIMULUS IS STRONG ENOUGH
absolute refractory membrane response
NO MATTER HOW STRONG, THE MEMBRANE WONT RESPOND
ABSOLUTE REFRACTORY PERIOD
ABSOLUTELY NO NEW Action Potential CAN HAPPEN.
absoulute refractory happens when?
DURING DEPOLARIZATION
relative refractory happens when?
DURING REPOLARIZATION
RELATIVE REFRACTORY PERIOD
WELL, MAYBE CAN HAVE A NEW Action Potential ...HAS TO BE AT -55MV AND BE STRONG STIMULUS.
absolute refractory channels
WHEN SODIUM CHANNELS ARE STILL OPEN
relative refractory channels
WHEN SODIUM CHANNELS CLOSED, BUT POTASSIUM CHANNELS OPEN
