Now, the post synaptic cell is basically the cell that is adjacent to our synapse, to our axon terminal that receives that signal in the first place. And the space, the region between this bulb like structure and our postsynaptic cell is known as our synaptic cleft. Now, this entire region is also sometimes known as the synapse and we're going to discuss the details of the synapse and how it actually works in a future lecture. So we have these important structures, the dendrites, the cell body or the soma the axon hill at the axon and the axon terminal, also known as our synapse or synaptic terminal. And all of these neurons contain these types of structures. Now let's actually briefly discuss the propagation of the electrical signal from the beginning to the end of our neuron.
