 It's time for a giant cranial nerve review. Doesn't that make you excited? You better say yes. Here's what the review is going to look like. I'm going to draw my pons. You getting the idea? I'm going to draw my medulla oblongata. Mmm. Look at that lovely medulla oblongata now. I'm going to draw my cranial nerves. And this time, I'm going to color code everybody. And I'm going to color code it by what kind of fibers are found in there. I'm going to then go back. I'm going to do sensory, motor, or both. And then I'm going to go back and mark the ones that carry visceral motor fibers. Are you ready? Remember our little antenna out here in front. That was cranial nerve number one. Remember we had a nice little X going on. That's cranial nerve number two. And then we have, whoa, I almost got so excited. I did not change my color. We have two little fellers coming out of the top of the pons. And this is cranial nerve number three, all motor. Cranial nerve number four is also a motor guy. Cranial nerve number five. Cranial nerve number five is the big trigeminal. That was fast. Whoa. Okay, something like that. And why did I make three little arms? Fingers, three fingers, three fingers. That's why I did it. Cranial nerve number, oops, I lost track of my numbering. Didn't die. Cranial nerve number four and five and six is also just motor. Just motor. That guy's not cool. Seven, what do you know about seven? Seven is definitely a boather. Seven is coming out here. Eight, eight, oops, dang it, I did it again. Seven, who was seven? Facial. Eight, vestibulococlear, all sensory. Coming out about her. Nine, nine is a boather. Ten is a boather. Look at me go. Nine, ten. Are you looking at me go? Dude, really, please go. I know that's not really what you're thinking. Who's this? Oops, dang it. Why did I erase number 11? Because it has to be red. Number 11 is accessory. Remember moving neck muscles because it is all motor and it's an accessorizer, right? You feel totally accessorized right now. And then 12. 12 was hypoglossal and that was just doing tongue. Remember it comes back in here and does that weird thing. There you go. That's a nice little picture. If you can visualize all of your colors, you could totally rock that picture right there. Are we finished? No, because we actually have to also mark that number two is carrying visceral motor fibers. And remember that was three. Oculomotor makes you your pupils constrict. Facial makes you salivate and cry. Glossopharyngeal makes you salivate. And Vegas does everything else, everything. Wow. Cranial nerves, holy nerves. You just did all the spinal nerves. Plexuses and you did all the cranial nerves. That's a lot of nerves and now the exciting thing is, I hope you feel excited right now. The exciting thing is we can do pathways and we have highways to travel on. So we're going to go out. We're going to get sensory information in. We're going to be able to process it. We know where we're going to process it in our central nervous system. We can know the highway that we're going to travel to get out to make stuff happen out there. You guys are like pathway, nervous system, rock stars. Unless you think pop stars are cooler and then you can be a pop star. I, on the other hand, am going to go to bed now.
