Document Summary

Table 4. 10 enormous amounts of collagen fibers practically no ground substance. Regular fibers running parallel to each other from where force comes from. Because there are only a few cells in the tissue. So if you have just a few cells than you don"t need much nourishment going on; just have to keep the cells alive & functioning. Fibroblasts make the fibers & maintain the fibers. After tissue is made, all you need is fibroblasts to repair & maintain. Ligaments connect bone to bone [90%] Takes long time to heal if injured tendon/ligament because it has a very poor blood supply, just enough blood to nourish the fibroblasts and there are not many fibroblasts there to begin with. Fibers are supposed to last forever; so just enough to maintain those that are there. Lots of fibers all kinds of different directions (random) Fibers in tissues are arranged parallel in the direction the force comes from/movement occurs.
