Question

Put the events for action potential generation in a neuron in the correct order (From 1-9) 

< Presynaptic axon terminal releases neurotransmitter Repolarization of the axolemma occurs as K+ leaves the cell Neurotransmitter binds to receptors on the postsynaptic cell K+ channels close slowly, causing hyperpolarization at the axolemma lon channels in the postsynaptic cell (dendrites or cell body) open allowing Na and K diffuse along their concentration gradient Sodium potassium pump continues to pump 3 Na* out of the cell and 2 K+ into the cell in order to restore ionic concentrations, allowing the axolemma to return to the resting membrane potential (polarized) The axon hillock reaches threshold, causing voltage-gated sodium channels to open and creates a complete reversal of charge (action potential) Depolarization of the membrane occurs and moves towards the axon hillock As the action potential travels down the axon, Na+ channels close and K+ channels open
