 Hello, buddy, Andrea here. So quick study topic today is going to be the tongue papilla. Thankfully, you don't have to go crazy about this. You just have to know the different kinds and where they're located and basically what they typically look like as well. So you're going to have the circumvalent papilla. Those are the ones more posterior, so towards the back. That's the easiest way to think about them, more posterior. And then you're going to have the folate papilla. You can't really tell here, but those are at the side of the tongue. And what you have to know is you typically have to take the tongue and like look to side to side in order to see those. Even if the patient sticks out their tongue, you can't really see them. You have to look, my tongue looks kind of red there, didn't it? That was weird. I think it was just the lighting. Anyway, I hope I made you guys laugh. Anyway, so the side of the tongue, you have to get the patient to stick out their tongue but then you do have to look closely at the sides. I'm talking about this papilla a lot, the common sight for oral cancer, you guys. If you see a concern on the side of the tongue, not good, but the earlier it's caught the better, which is why it's so important during our oral cancer screenings to check the tongue and the side of the tongue as well. But you should also know this papilla is very prominent in children. So in children, it's going to look like a big red lump, but that's not a bad thing. That's just common for children. But if you see a big red lump in say a 20 year old that might not be normal, keep an eye on it, okay? And then you have the Philly form papilla. Those are kind of in the middle of the tongue off to the sides a little bit, but not as far back as the circumvallate papilla. And then at the tip of the tongue, closer to the anterior, last but not least, the fungi form papilla, okay? Those are the main ones you have to know. So just to talk about them one more time from last to, or from the one that I just talked about to the first one. So this one here is closer to the anterior off to the sides a little bit, but closer to the anterior. The next one is kind of off to the sides, closer to the middle. Pholate papilla is the one that's on the side of the tongue and the circumvallate papilla is at the back more posterior. In this image here, they talk about the lingual tonsil and the palatine tonsil. They don't usually ask too much about the tonsils on the board exam unless they're talking about the anterior tonsil or pillar and the posterior tonsil or pillar. I'm going to leave that for another video because then we sort of go into a couple other things. We talk about the saliva, you know, other things, but this is the basics that you have to know for the tongue papilla, nothing more and nothing less. So thank you guys for watching. Let me know if any questions and I'll see you guys in the next one.
