Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix. Histology. Elastic fibre, any of the yellowish branching fibres composed primarily of the protein elastin, frequently arranged in plates or perforated membranes, as in the walls of the large arteries. Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. 2A and B, arrows) in these specimens were thin and parallel to the collagen fibers and located near the tenocytes. Reticular fibers are the third type of protein fiber found in connective tissues. These fibers form bundles that appear dark under a … Elastic fibers in most grade II specimens were disarranged (circle) and fragmented. Elastic fibers stain well with aldehyde fuchsin, orcein, and Weigert's elastic stain in histological sections.. The principal protein is elastin. Elastic cartilage looks very similar to hyaline cartilage under a microscope, and special stains must be used to show the otherwise invisible elastic fibers that give this particular cartilage type its name.Like hyaline, elastic cartilage also has single or multiple chondrocytes housed within spaces called lacunae. Elastic Cartilage. Elastic fibers of the connective tissues form a network which is responsible for the elasticity of various organs. Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix. Unlike collagenous fibres, they show no orderly fibrous subunits under microscopic examination but sometimes elastic fibers. Elastic fibers provide flexibility to the tissues. Abstract. Areolar connective tissue consists of fibers (collagen, elastic and reticular) and several types of cells (Fibroblasts, macrophages, adipocytes, mast cell, plasma cell and other kinds of blood cells). Definition: elastic protein that is a major component of elastic fibers; Characteristics. The relative concentration of elastic fibers is highest in ligamentum nuchae, and they are abundantly present in aorta and associated blood vessels (Table 1). LOOSE CT and DENSE CT. Elastic Cartilage. Elastic fibers are made of the protein elastin; this fiber can stretch to one and one half of its length, returning to its original size and shape. However, degeneration and disruption of the elastic fibers was specifically observed in the grade II specimens (Fig. this fiber can stretch up to 1.5 its length and still go back to its original shape. this fiber is springy. The permanganate-bisulfite-toluidine blue reaction is a highly selective and sensitive method for demonstrating elastic fibers under polarizing optics. The principal protein is elastin. elastic fibers. The induced birefringence demonstrates the highly ordered molecular structure of the elastin molecules in the elastic fiber. Elastic fibers - fibers responsible for the flexibility of the tissue: Location: Dermis, lamina propria of the digestive and respiratory tracts, mucous membranes of reproductive and urinary tracts, glandular stroma, mesentery: Clinical relations: Fibrosis, scarring, keloids, carcinoma staging: Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. Connective tissue can be categorized into these 4 subcategories. Areolar connective tissues are one of the most distributed connective tissue. Elastic fibers provide flexibility to the tissues. Connective Tissue Proper, Cartilage, Bone, and Fluid. Regular elastic fibers (Fig. These fibers form bundles that appear dark under a … This fiber consists of thin strands of collagen that form a network of fibers to support the tissue and other organs to which it is connected. 2C).
