Now, any given neuron accepts an electrical signal on the dendrites and it sends that electrical signal through the cell body and, and into the exxon hill lock. On the exxon hill lock, the action potential is generated and it moves along the axon and until the end of that axon. Now, at the end of each axon, we have extensions, and on the end of each extension, we have a knob like structure that looks like the knob of a door. So this is this structure here. Now, this structure goes by many names. Some of these names include the axon terminal, the synaptic terminal, or the synaptic.
