And the soma is the region of the cell that stores the nucleus and other organelles. For example, the endoplasmic reticulum, the Golgi apparatus armitochondria and so forth. Now, the region between this long extension known as the axon and the cell body is something called the exxon hill lock. 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.
