[Voiceover] This slide is fibrocartilage. Now the current magnification is 100x total magnification. What we're looking for are the cells and the various features that will identify this as fibrocartilage, and help you differentiate fibrocartilage from elastic or hyaline cartilage. So what we're looking at is this more off-white coloration. This is the actual fibrocartilage. This pink stuff on the side over here is not fibrocartilage, so we're gonna focus on this area. So if we zoom in a little bit, now what we can start to see here is the individual chondrocytes. So these cells inside are the chondrocytes. In cartilage, the chondrocytes are surrounded by a lacuna. This structure is the lacuna. So here we have a chondrocyte within the structure of lacuna. Here's another one, chondrocyte within lacuna. You can kinda think of the chondrocyte as in a home, inside its house, lacuna. The only difference is, the chondrocyte's under house arrest. The chondrocytes are stuck within the lacuna, they stay there and are permanently kept. So now that we have the cells and the structures, how do we know this is fibrocartilage? In fibrocartilage, the matrix, which is what is in-between the cells should have a little bit of lines, kind of like a pattern to it. Where in hyaline cartilage, it would be this kind of misty color, we don't see any pattern. In elastic cartilage, you should've seen the actual fibers. But in this fibrocartilage, you can kind of see how it's all going in one direction, so all the fibers kind of running this one direction, going up. So this is your fibrocartilage.
