Inside the cell: Negative 2. Depolarization: Sodium starts flowing in, inside the cell: positive 3. After depolarization comes repolarization, where the sodium channel close, and the potassium channel opens. Outflux of potassium brings cells back to more negative than the initial state (Hypoerloarization). This is the refractory period Conduction of action potential through a nerve axon. - Continous Conduction (Unmyelinated) - Saltatory Conduction (Myelinated) All-Or-None Law - Either we get a action potential, or not. - Chemical Synapse with Ligand gated channels, or chemically gated channels - Excitatory or Inhibitory #nervephysiology #physiology #nerve #neuron #actionpotential$
