So the exxon hillock basically connects the exxon to the cell body and the exxon hill lock is really a specialized section of the cell body that is actually capable of generating an action potential. And the action potential is basically a voltage difference that allows an electric signal to be sent along the exxon from our cell body. Now, the exxon is a long extension of our nerve cell that is specialized to actually carry or propagate that electrical signal that is generated in our exxon hillock and it carries that electrical signal away from the sole or from the cell body and to the end of the axon known as the exxon terminal. Now, the exxon terminal is also known as the synaptic terminal or the synaptic bouton. And the axon terminal consists of projections at the end of our exxon that basically are specialized to transmit our electrical signals to other cells either by electrical or chemical means. Now, if we actually zoom in on any one of these projections we get the following bulb like structure.
