Groups:
(a) Resting Potential
,
(b) Depolarization
,
(c) Repolarization
,
(d) Hyperpolarization to Resting potential
K+ pumps open
-75mV --> -70 mV
Na+ floods the neuron
Caused by a stimulus
Na+/K+ pumps reopen maintaining 3Na+ outside to 2K+ inside the neuron
Na+/K+ pumps open
Prior to stimulus
back to rest awaiting another stimulus to occur.
Na+ open
K+ leaves the neuron.
+40 mV --> -75mV
-55mV --> +40mV
meets threshold of -55mV
-70mv
