And the last part of the Science Trivia Corner for this evening is the trivia section. Just one straight piece of trivia for you tonight that you might find interesting. The nerve cells in the body are actually found in the spinal cord. And these are the alpha motor neurons. And they're responsible for sending signals from the muscles, getting the muscles moving, etc. And that signal is traveling at about 260 miles per hour. It doesn't sound like a lot, but considering the very short distance that the signals have to travel, it's moving along very, very fast. You're not noticing any real lag in the time in which the nerve is sending a signal to a spinal cord destination. But if you were to take all those nerves, these alpha motor neurons, and put them into hand, they would extend several thousands of miles. And if you were to wrap it, let's say you were to wrap it around the equator, it would take 3.8 days for a signal to go completely around the world. I mean, it's a long time. But short distances through our body, time is minutes.
