Bio help please!! what is the sequence of events that follow to bring about the excitation of the next neuron?
A neuron releases acetylcholine (a neurotransmitter) at a junction. What is the sequence of events that follow to bring about the excitation of the next neuron?

The Ach travels accross the synaptic cleft, binds to the nicotinic receptor on the postsynaptic neuron, which opens a sodium channel, influx of sodium depolarizes the cell, when brought to threshold, the postsynaptic neuron sends an action potential down the axon to the synaptic bulb/terminal.
