all right then we have the three types of loose fibrous connective tissue um and so all three of these are gonna have less dense um matrix molecules so um if they're using either collagen or elastin or reticular fibers which is another type they're going to be less dense um so there'll be more open spaces or cells or other things taking up the space so the first type is the reticular connective tissue and i'm using a black marker because basically reticular tissue will stain as really dark almost black and that's one of the easiest ways to tell that it is reticular tissue and what you're going to see is this black tissue and lots of open space in between you'll see some fibroblasts within which are cells that make these fibers reticular connective tissue is often found in soft organs because it forms sort of a scaffolding or structure to the soft organs but it leaves enough space for things like your immune cells or other cells to get through the tissue which is going to be important for many of those organs the next tissue type are areolar and areolar is going to have a lot of these collagen fibers and other fibers but they're going to be much more sparse than you saw and saw in the dense connective tissues um and you'll see some fibroblasts and other cells within them but you'll see it usually stains pretty red and there's just a lot more open space one of the places areolar tissue is found is in the basement membrane underneath some episodes uh some skin layers so um underneath some layers of cells you'll find this um just this it's a nice um uh matrix that cell epithelial cells can sit on and allow it to attach to and helps it to attach to underlying layers the third type are adipose tissue adipose tissue um you'll see mostly the cells themselves and i'm not really good at drawing them they're almost like a honeycomb shape or they look like if you've seen like a um a bunch of bubbles stuck together and you see wherever they the cells touch each other you see a flat side um but it's not necessarily square i'm just not good at drawing it you'll see a nucleus sort of push to the side um and actually this if you're seeing them living then you'll see the nucleuses side and what's in most of the space within these big shapes is fat tissue so if you look at a diagram this might look yellow because they usually color the fat yellow if you look at a cut of meat the meat of that on the meat will often look yellow if you are looking at a slide a histology slide because of the way they rinse the slides the fat will rinse away so it'll just look like empty space but that's adipose tissue that's just found in fat like um anywhere like in you know in under your skin in the um uh hypodermis or subcutaneous layers um or just in fatty areas of the body and you see and all three of these are considered loose they do um they are under the fibrous although the adipose is going to have less fibers than the other two types but it's still under that same category
