 Now we get to do all the rest of our facial bones. And so I, because well, maybe I'll try drawing a little line so that you can see each one that I'm actually talking about. These are all on the face, so they're not part of the cranium. You've already, we've already talked about this one. What is it? We didn't go into detail. It wasn't on one of our lists. But we agreed that it made up part of our cheekbone, and it formed a joint with the temporal bone. This is your zygomatic bone. Now, who is this? That's maxilla. Who's this? That's mandible. Those are all facial bones. Who's this? What? That's not a facial bone. Silly. That's the temporal bone, eh, eh, okay. But now, inside your eye socket, seriously are a whole bunch of bones. Now, look at this little guy. This is your lacrimal bone. It kind of makes sense. Lacrimation is the process of crying. And so the lacrimal bones are in the place where your tears are going to come out of your eyeballs. There's actually a hole in there. Dude, tell me that we have to know that hole on our lacrimal bones. Why don't we know the hole? I think we do have to know the hole when we get into the eyeball. I hope so, because that hole connects your eye to your nose. Oh my gosh, that's really cool. And that's why when you cry, this is your fast fact for anatomy day talking at the dinner table tonight with your family. Tell them that you know how when you cry, you snot all over the place? Like, your nose starts to run almost automatically. Dude, really? I just turn into this blubbering, red, snotty mess when I start to cry. That actually isn't snot. So you can feel better now about crying onto anyone's shoulder, because you're not actually snotting on them, even if the stuff comes out of your nose. Those are tears. You just are producing crazy too many tears. And those tears can't just be absorbed in your nose like they normally are. What? And so they come out because you just are like pouring fluid through the lacrimal canal out of your eye and into your nasal cavity. I love our bodies. They are so freaking cool. Okay, sorry about that. That's a tiny little bone, but there are a bunch of connections there that are very important. All right, who else do we have? Ah, this is easy. This is my nasal bone up here. Do you know that down here, why isn't it a nasal bone? It's made out of cartilage, dog. Let's look up in there. Let's look up inside this guy's nose. We have these little wads of gum smeared on the sides, the lateral sides of the nasal cavity. It's not really gum, so do not be confused. I don't recommend putting gum up your nose. Now, look at the shape of it. And keep in mind that here's another little shape, but guess who that is? Ethmoid bone. And remember the parts of the ethmoid bone? That's the middle nasal conchie. And that's the superior nasal conchie up there somewhere on your ethmoid bone. Who's that? That is the bone that makes up your inferior nasal conchie. And that's the one that we can see the best on Linda's half head, covered in tissue, of course, because we can't just see her bone sitting there. It'd be awesome to go in and look and see if we could find that bone underneath there. Guess what the name of the bone is? You're going to love me. You really are, every now and then you do. It's the inferior nasal conchie bone. Is that true? Now that I say that, yes, it's the inferior nasal conchie bone. That's true. So there it is. Now, of course you wonder, what is making up the nasal septum? Like, why can't I stick my finger up my nose and then go all the way over and then come back out on the other side? This is why that whole like snorting pot, not pot snorting bit, that pot thing that you have water in it. I don't know what that thing is called. So you're supposed to snort water, fluid saline into one side and then you're supposed to drip it back out the other. I know I would drown if I tried to do that, but you have to go back far enough in your nasal cavity that you get around these two bones that make up your nasal septum. One of them is the perpendicular plate of the ethmoid bone. And the other one is its own separate bone. See how it's a new color? And it's called the vomer. The vomer and the perpendicular plate together make up the nasal septum, which is why I can't just snort my water in one side and out the other without going back into my like nasopharynx to get it, you know. That is not going to work for me. Did we name all our bones of our face? I think so. Oh, we did not. We have one more that we are not naming because we can't see it here. They're called palatine bones. Where are you going to look to find them? Dude, these, again, super easy unless, of course, you are tweaked out by the fact that, you know, in a real skull, it looks like just one hard palate. And so, no, this is maxilla, but in the very back, the most posterior edge of the maxilla, it forms a joint or a connection with the palatine bones. And now you know everything about all the bones in your face. In your face. Now let's talk about foramina. foramina, na, na, na, na, na. Feramina, na, na, na, na. I'll be right back.
