You will never see reticular connective tissue alone--there will always be other cells scattered among the reticular cells and reticular fibers. Specialized cells are involved in the formation of new reticular fibers and the maintenance of existing fibers that are already part of the collagen lattice in the reticular connective tissue. Forms a supporting structural framework; white blood cells remove … What are the Different Types of Human Tissue. This allows for free exchanges between cells, while still providing a reinforcing framework that will support an organ or lymph node. Reticular fibers are thinner than collagen fibers. Collagen fibres are the most widespread and made up of fibrous protein, collagen. Reticular Connective Tissue:the reticular connective tissue is predominatly made up of reticuler fibers and characterized by a cellular framework as seen in lymphatic tissues and bone marrow. The fibers provide support and stability to other types of cells. The collagen fibers are external to the reticular fibers forming bundles. Medical definition of reticular fiber: any of the thin branching fibers of connective tissue that form an intricate interstitial network ramifying through other tissues and organs. The fibers’ dimensions and organizations result in several types of connective tissues, one being loose connective tissue. Viewed up close, the reticular fibers can be seen in the form of a series of branching threads. Structure. Reticular layer of Dermis. Like other types of tissue in the body, the reticular connection tissue is constantly broken down, recycled, and replaced with new tissue. 2. What is the function of reticular tissue? Connective tissue can further be broken down into three categories: loose connective tissue, dense connective tissue, and specialized connective tissue. The basal lamina is secreted by the cells of the epithelial tissue itself and contains proteins, glycoproteins, and collagen IV, a type of structural protein that forms sheets.
