While this might sound scary, these fractures are actually very easy to treat in most cases. The exception to this rule is extensive avulsion fractures, and certain types of fractures in children.
This connective tissue contains collagen fibers for flexibility and strength, and numerous elastic fibers that enable it to be stretched. Alveolar connective tissue is found in the skin and in most internal organs of vertebrates, where it allows the organs to expand, which is essential for the lungs.his connective tissue contains collagen fibers for flexibility and strength, and numerous elastic fibers that enable it to be stretched.

The most abundant fiber in connective tissues is a tough protein called collagen. Tendons, ligaments, and the white stringy tissue (fascia) seen in some cuts of meat are composed almost entirely of collagen, as is leather, which consists of the connective tissue layer (dermis) of animal skins.ollagen also strengthens bone and cartilage. Elastic and reticular fibers are less abundant connective tissue proteins with a more limited distribution. The ground substance may be liquid, as in blood; gelatinous, as in areolar tissue; rubbery, as in cartilage; or calcified and stony, as in bone.
