Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow. Reticular Fibers Reticular fibers are composed of type III collagen.

These produce reticular fibers arranged in an interlaced network (reticulum), similar to dense irregular connective tissue. A.

It contains all three types of fibers (collagen, elastic, and reticular), which are distributed randomly and crisscross in all directions, as shown in Figure 1. Function: Fibers form a soft internal skeleton (stroma) that supports other cell types including white blood cells, The areolar tissue contains collagen fibers, reticular fibers and a few elastic fibers embedded in a thin and almost fluid-like ground substance. Reticular fibers protect lymph organs, hold together adipose tissue, and form the soft skeleton. Adipose connective tissue A thin connective tissue capsule surrounds the thymus; blood vessels enter the thymus through the capsule and its septa. ["contains collagen fibers arranged "regularly" in bundles", B."fine interlacing network of reticular fibers and reticular cells", C."fine interlacing network of elastic fibers and chondrocytes"] What is the location where this tissue can be found? Connective tissue is made up of a few cells present in the intercellular framework of protein fibres secreted by the cells, known as collagen or elastin. Reticular connective tissue is named for the reticular fibers which are the main structural part of the tissue. Connective tissue is a term used to describe the tissue of mesodermal origin that that forms a matrix beneath the epithelial layer and is a connecting or supporting framework for most of the organs of the body.

Surrounding the lymph node is a capsule of collagen fibers (type I collagen) stained red. Fibroblasts are the main cells of connective tissue. Reticular connective tissue is the unique or modified form of connective tissue proper that has reticular fibers (tiny and branching fibers) and cells. The final component of connective tissue are the fibers.In this H&E stained slide, collagen and fibroblasts are seen in the capsule of this organ (lymph node). Scattered among the spaces within the fibers are numerous reticular cells (lymphocytes). The reticular dermis is the lower layer of the dermis, found under the papillary dermis, composed of dense irregular connective tissue featuring densely packed collagen fibers.

Reticular connective tissue 40X Reticular connective tissue is named for the reticular fibers which are the main structural part of the tissue. Clusters of mesenchymal cells are scattered throughout adult tissue and supply the cells needed for replacement and repair after a connective tissue injury. Some examples of structures in the body that include this type of . However, some scientists believe areolar tissue is actually a subtype of loose tissue, along with adipose and reticular tissue. The reticular fibres are mostly made up of type III collagen (100-150 nm in diameter), which is produced by reticular cells, which are unique fibroblasts.

.

The major organs associated with this system are the bone marrow, intestines, kidney, spleen, and liver. connective tissue: [ kō-nek´tiv ] a fibrous type of body tissue with varied functions; it supports and connects internal organs, forms bones and the walls of blood vessels, attaches muscles to bones, and replaces tissues of other types following injury. Their function is to form a stroma and provide structural support, such as that in the lymphoid organs, e.g. shows: a network of reticular fibers (black) that provides a supporting framework for soft organs like the spleen, liver and lymph nodes.

It holds organs in place and attaches epithelial tissue to other underlying tissues. Its subunits, the reticular fibers, are predominant structures in the human body, but they are mainly scattered and mixed with other types of fibers. Lipid is preserved and stained black when the tissue is prepared using osmium tetroxide as a fixative. It is the primary location of dermal elastic fibers.
