 Okay, so we're looking at the tongue here. So here's our tongue. Okay, so your tongue has three, what are called papillae. Okay, so these are these raised regions. So we can see back here, you have these circunvila papillae. So they're just in the back of the tongue here. They're very large, and they contain a large number of taste buds, okay? Now, if you look closely, you can see these individual larger dots here. These are our fungiform papillae, because they kind of look like the heads of fungus, mushroom heads. Okay, those also contain not as many, but taste buds associated with them. And then everything else here, you can see it's very rough in between. That's filiform papillae. So these don't have taste buds, they're there mainly for friction so that you can aid in swallowing.
