Question

Match the events listed with their order in the mechanisms behind the firing of an action potential under normal conditions (without tetrodotoxin present in the man's body).  The cell has a resting membrane potential of -65 mV.

You should match these events at the initial segment of a bipolar neuron.

Please note that this is a sequence question.

Although not an option below, you should consider that neurotransmitters are bound to ligand-gated receptors causing EPSPs. Now, put the process in the correct sequence:

**arrange from 1-10
