Axonal transport

For example, that was the first time that I think I had really gotten a good understanding of...

Some of the other factors of nerve physiology, such as axonal transport, you know, the movement of this idea that a nerve cell, which again still boggles my mind, is huge in terms of its length because it goes from the dorsal horn all the way to the tip end of wherever that nerve tends to end.

On adults, you can have a three-foot axon going down to your big

toe from your seat.

Which is really crazy.

And in order for that axon to work properly, it has to transmit nutrient proteins and other substances throughout the length of that whole axon.

This is done by a channel or a process within the nerve called axonal transport, and it moves this axon.

fluid called axoplasm throughout the length of the nerve in one direction and then back in the other direction to sort of clear it clear it back out
