Connective Tissue occurs partly in the form of stout cords—ligaments—which bind different bones together ; or which, called tendons, attach muscles to bones. It also supplements the coarser bony skeleton by a finer one, which extends as a fine network through all the soft parts of the body, making a sort of microscopic skeleton for its cells, and being laid down as a soft packing material, a good deal like raw cotton, in the crevices between different organs, as shown at s, Fig. 3, where it is seen between the muscles of the forearm. This tissue is, in fact, so widely spread over the body, from the skin outside to the lining of the alimentary canal within, that if we could employ a solvent which would corrode away all the rest, and leave only the connective tissue, a very perfect model of all the organs would be left; something like a skeleton leaf, but far more minute in its tracery.

What is a ligament? A tendon? Of what are ligaments and tendons composed ? Where else do we find connective tissue ?
