Older textbooks typically refer to elastic and reticular connective tissues as specialized connective tissues. Reticular connective tissue is a type of loose irregular connective tissue and has a network of reticular fibers (fine type III collagen) that form a soft skeleton (stroma) to support the lymphoid organs (lymph nodes, red bone marrow, thymus, and spleen. Connective tissue is one of the four types of tissue in traditional classifications (the others being epithelial, Muscle, and Nervous tissue) Collagen type III alpha 1 (Ehlers-Danlos syndrome type IV autosomal dominant, also known as COL3A1, is a human Gene. In animal tissue stroma (from Greek στρώμα meaning “bed” refers to the connective non-functional supportive framework of a biological cell, tissue A Lymph node ( lɪmf noʊd is an organ consisting of many types of cells and is a part of the Lymphatic system. Bone marrow is the flexible tissue found in the hollow interior of Bones In adults marrow in large bones produces new Blood cells It constitutes 4% of In Human anatomy, the thymus is an organ located in the upper Anterior portion of the chest cavity just behind the Sternum. The spleen is an organ found in all Vertebrate animals In humans the spleen is located in the abdomen of the body where it functions in the destruction of redundant Red ) Reticular fibers are synthesized by special fibroblasts called reticular cells. Reticular fibers or reticulin is a histological term used to describe a type of Structural fiber composed of Type III collagen. A fibroblast is a type of cell that synthesizes and maintains the Extracellular matrix of many Animal tissues A reticular cell produces Reticular fibers and surrounds the fibers with its Cytoplasm, which isolates the fiber from other components of the tissues or The fibers are thin branching structures.
Adipose tissue is held together by reticular fibers. "Adipose" redirects here For the Doctor Who monster see " Partners in Crime "
They can be identified in histology by staining with a heavy metal like silver or the PAS stain that stains carbohydrates. Histology (from the Greek = 'tissue' is the study of the microscopic anatomy of cells and tissues of Plants and Silver (ˈsɪlvɚ is a Chemical element with the symbol " Ag " (argentum from the Ancient Greek: ἀργήντος - argēntos gen Periodic acid-Schiff ( PAS) is a Staining method used in Histology and Pathology. Carbohydrates (from ' Hydrates of Carbon ' or saccharides ( Greek σάκχαρον meaning " Sugar " are the most
Reticular connective tissue resembles areolar connective tissue, but the only fibers in its matrix are reticular fibers, which form a delicate network along which fibroblasts called reticular cells lie scattered. Although reticular fibers are widely distributed in the body, reticular tissue is limited to certain sites. It forms a labyrinth-like stroma (literally, "bed or "mattress"), or internal framework, that can support many free blood cells (large lymphocytes) in lymph nodes, the spleen, and red bone marrow.
There are more than 20 types of reticular fibres. In Reticular Connective Tissue type III collagen/reticular fiber (100-150nm in diameter) is the major fiber component. It forms the architectural framework of; liver, adipose tissue, bone marrow, spleen, basement membrane to name a few
