Eventually it reaches these bulb like structures that we discussed earlier. Now this will usually stimulate our bulb like structure to release vesicles that carry neurotransmitters into this region. And then these neurotransmitters will bind to postsynaptic cell receptors, also known as effective cell receptors, on the cell membrane of this postsynaptic cell. Now this in turn will usually cause changes to the membrane permeability of the postsynaptic cell and that in turn will generate some type of signal that will be passed down to the postsynaptic cell. And this is usually how the propagation of the electrical signal actually works along our nerve cell. And we'll discuss this in much more detail in the next several lectures.
