In most cases, you won't have a neuron that's just sitting on its own. They will be clustered together in a nerve. The median nerve is going to try to speed that signal up for you. And so what it does, just like you see with a power cord, you don't have the power cord coming out of your power socket that's just exposed copper-wise. Right? So do we insulate our neurons, Matthew? We use mylon. That's just fat. We just wrap it up with fat. Yeah. In the peripheral nervous system, that is what we call a swan cell. Which always reminds me of the Adam Sandler, Billy Madison.
