Top 10 facts about the world. An avulsion fracture is a type of fracture in which part of the bone is broken off or âavulsedâ from the rest of the bone. 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.

Collagen fibers made of collagen. Collagen fibers are tough and only slightly elastic.. They often occur in bundles with the fibers parallel to one another, which gives great tensile strength. Collagen is found in most connective tissues, esp. bone, tendons, and ligaments.Elastic fibers are composed of a protein called elastin and glycoprotein framework. They are very stretchy and branch and join to form a network. They provide strength to tissues, but allows the tissue to be flexible and stretchy.ense irregular connective tissue-also has collagen fibers and fibroblasts, but the collagen fibers are thicker and arranged irregularly. This tissue usually forms sheets, and resists pulling in many directions. It is found in heart valves, around cartilage, bone, muscles, dermis of skin, and around some organs.
