The membrane thought it would form a selective wall
Not let Sodium in at all
But along came acetylcholine
Sat on its receptor named after nicotine
And forced the beginning of a positive free-for-all.
And so was set the podium
For the opening of of the voltage gated channels for Sodium
But the neuron thought it would be unfair
For Sodium to have all the fun's share
And so opened the channels for potassium.
The results of this normalization
Was that the cell saw hyperpolarization
But the membrane thought it would be prudential
To return to its resting potential
Ans so soon it reached its native configuration.
