Document Summary
Reticular fibers are important because they make up the network upon which cells of fibers rest on. Lots of branching of type 3 collagen fibers. All organs have these networks spleen filters out old or damaged blood cells (senescent old) Reticular fibers are stained with silver therefore are called argyophillic. Elastic fibers are important because that ability to recoil is important! They contain elastin that is scaffolded onto fibrillin. Fibrillin creates structure scaffold on which elastin fibrils are arranged. Easy way to think of it : spandex 100% cotton shirt and you wear it and stretch it out of shape but elastic fibers that have hint of spandex that help to maintain shape of things. Just like spandex you don"t need a lot of it but a little bit of it just for the hold of it. Fibrillin is extremely susceptible to photo aging damage by uv light.
